+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+  advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies within all project spaces, and it also applies when
+an individual is representing the project or its community in public spaces.
+Examples of representing a project or community include using an official
+project e-mail address, posting via an official social media account, or acting
+as an appointed representative at an online or offline event. Representation of
+a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at ohmyzsh@planetargon.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.

+# CONTRIBUTING GUIDELINES
+
+Oh-My-Zsh is a community-driven project. Contribution is welcome, encouraged, and appreciated.
+It is also essential for the development of the project.
+
+First, please take a moment to review our [code of conduct](CODE_OF_CONDUCT.md).
+
+These guidelines are an attempt at better addressing the huge amount of pending
+issues and pull requests. Please read them closely.
+
+Foremost, be so kind as to [search](#use-the-search-luke). This ensures any contribution
+you would make is not already covered.

+
+## Reporting Issues
+
+### You have a problem
+
+Please be so kind as to [search](#use-the-search-luke) for any open issue already covering
+your problem.
+
+If you find one, comment on it, so we know more people are experiencing it.
+
+If not, look at the [Troubleshooting](https://github.com/ohmyzsh/ohmyzsh/wiki/Troubleshooting)
+page for instructions on how to gather data to better debug your problem.
+
+Then, you can go ahead and create an issue with as much detail as you can provide.
+It should include the data gathered as indicated above, along with the following:
+
+1. How to reproduce the problem
+2. What the correct behavior should be
+3. What the actual behavior is
+
+Please copy to anyone relevant (e.g. plugin maintainers) by mentioning their GitHub handle
+(starting with `@`) in your message.
+
+We will do our very best to help you.
+
+### You have a suggestion
+
+Please be so kind as to [search](#use-the-search-luke) for any open issue already covering
+your suggestion.
+
+If you find one, comment on it, so we know more people are supporting it.
+
+If not, you can go ahead and create an issue. Please copy to anyone relevant (e.g. plugin
+maintainers) by mentioning their GitHub handle (starting with `@`) in your message.
+
+## Submitting Pull Requests
+
+### Getting started
+
+You should be familiar with the basics of
+[contributing on GitHub](https://help.github.com/articles/using-pull-requests) and have a fork
+[properly set up](https://github.com/ohmyzsh/ohmyzsh/wiki/Contribution-Technical-Practices).
+
+You MUST always create PRs with _a dedicated branch_ based on the latest upstream tree.
+
+If you create your own PR, please make sure you do it right. Also be so kind as to reference
+any issue that would be solved in the PR description body,
+[for instance](https://help.github.com/articles/closing-issues-via-commit-messages/)
+_"Fixes #XXXX"_ for issue number XXXX.
+
+### You have a solution
+
+Please be so kind as to [search](#use-the-search-luke) for any open issue already covering
+your [problem](#you-have-a-problem), and any pending/merged/rejected PR covering your solution.
+
+If the solution is already reported, try it out and +1 the pull request if the
+solution works ok. On the other hand, if you think your solution is better, post
+it with reference to the other one so we can have both solutions to compare.
+
+If not, then go ahead and submit a PR. Please copy to anyone relevant (e.g. plugin
+maintainers) by mentioning their GitHub handle (starting with `@`) in your message.
+
+### You have an addition
+
+Please [do not](https://github.com/ohmyzsh/ohmyzsh/wiki/Themes#dont-send-us-your-theme-for-now)
+send themes for now.
+
+Please be so kind as to [search](#use-the-search-luke) for any pending, merged or rejected Pull Requests
+covering or related to what you want to add.
+
+If you find one, try it out and work with the author on a common solution.
+
+If not, then go ahead and submit a PR. Please copy to anyone relevant (e.g. plugin
+maintainers) by mentioning their GitHub handle (starting with `@`) in your message.
+
+For any extensive change, such as a new plugin, you will have to find testers to +1 your PR.
+
+### New plugin aliases
+
+We acknowledge that aliases are a core part of Oh My Zsh. There are plugins that have +100 aliases!
+
+This has become an issue for two opposing reasons:
+
+- Some users want to have their personal aliases in Oh My Zsh.
+- Some users don't want any aliases at all and feel that there are too many.
+
+Because of this, from now on, we require that new aliases follow these conditions:
+
+1. They will be used by many people, not just a few.
+2. The aliases will be used many times and for common tasks.
+3. Prefer one generic alias over many specific ones.
+4. When justifying the need for an alias, talk about workflows where you'll use it,
+   preferably in combination with other aliases.
+5. If a command with the same name exists, look for a different alias name.
+
+This list is not exhaustive! Please remember that your alias will be in the machines of many people,
+so it should be justified why they should have it.
+
+----
+
+## Use the Search, Luke
+
+_May the Force (of past experiences) be with you_
+
+GitHub offers [many search features](https://help.github.com/articles/searching-github/)
+to help you check whether a similar contribution to yours already exists. Please search
+before making any contribution, it avoids duplicates and eases maintenance. Trust me,
+that works 90% of the time.
+
+You can also take a look at the [FAQ](https://github.com/ohmyzsh/ohmyzsh/wiki/FAQ)
+to be sure your contribution has not already come up.
+
+If all fails, your thing has probably not been reported yet, so you can go ahead
+and [create an issue](#reporting-issues) or [submit a PR](#submitting-pull-requests).
+
+----
+
+## Commit Guidelines
+
+Oh My Zsh uses the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
+specification. The automatic changelog tool uses these to automatically generate
+a changelog based on the commit messages. Here's a guide to writing a commit message
+to allow this:
+
+### Format
+
+```
+type(scope)!: subject
+```
+
+- `type`: the type of the commit is one of the following:
+
+  - `feat`: new features.
+  - `fix`: bug fixes.
+  - `docs`: documentation changes.
+  - `refactor`: refactor of a particular code section without introducing
+    new features or bug fixes.
+  - `style`: code style improvements.
+  - `perf`: performance improvements.
+  - `test`: changes to the test suite.
+  - `ci`: changes to the CI system.
+  - `build`: changes to the build system (we don't yet have one so this shouldn't apply).
+  - `chore`: for other changes that don't match previous types. This doesn't appear
+    in the changelog.
+
+- `scope`: section of the codebase that the commit makes changes to. If it makes changes to
+  many sections, or if no section in particular is modified, leave blank without the parentheses.
+  Examples:
+
+  - Commit that changes the `git` plugin:
+  ```
+  feat(git): add alias for `git commit`
+  ```
+
+  - Commit that changes many plugins:
+  ```
+  style: fix inline declaration of arrays
+  ```
+
+  For changes to plugins or themes, the scope should be the plugin or theme name:
+
+  - ✅ `fix(agnoster): commit subject`
+  - ❌ `fix(theme/agnoster): commit subject`
+
+- `!`: this goes after the `scope` (or the `type` if scope is empty), to indicate that the commit
+  introduces breaking changes.
+
+  Optionally, you can specify a message that the changelog tool will display to the user to indicate
+  what's changed and what they can do to deal with it. You can use multiple lines to type this message;
+  the changelog parser will keep reading until the end of the commit message or until it finds an empty
+  line.
+
+  Example (made up):
+
+  ```
+  style(agnoster)!: change dirty git repo glyph
+
+  BREAKING CHANGE: the glyph to indicate when a git repository is dirty has
+  changed from a Powerline character to a standard UTF-8 emoji. You can
+  change it back by setting `ZSH_THEME_DIRTY_GLYPH`.
+
+  Fixes #420
+
+  Co-authored-by: Username <email>
+  ```
+
+- `subject`: a brief description of the changes. This will be displayed in the changelog. If you need
+  to specify other details, you can use the commit body, but it won't be visible.
+
+  Formatting tricks: the commit subject may contain:
+
+  - Links to related issues or PRs by writing `#issue`. This will be highlighted by the changelog tool:
+    ```
+    feat(archlinux): add support for aura AUR helper (#9467)
+    ```
+
+  - Formatted inline code by using backticks: the text between backticks will also be highlighted by
+    the changelog tool:
+    ```
+    feat(shell-proxy): enable unexported `DEFAULT_PROXY` setting (#9774)
+    ```
+
+### Style
+
+Try to keep the first commit line short. It's harder to do using this commit style but try to be
+concise, and if you need more space, you can use the commit body. Try to make sure that the commit
+subject is clear and precise enough that users will know what changed by just looking at the changelog.

+
+Oh My Zsh is an open source, community-driven framework for managing your [zsh](https://www.zsh.org/) configuration.
+
+Sounds boring. Let's try again.
+
+**Oh My Zsh will not make you a 10x developer...but you may feel like one.**
+
+Once installed, your terminal shell will become the talk of the town _or your money back!_ With each keystroke in your command prompt, you'll take advantage of the hundreds of powerful plugins and beautiful themes. Strangers will come up to you in cafés and ask you, _"that is amazing! are you some sort of genius?"_
+
+Finally, you'll begin to get the sort of attention that you have always felt you deserved. ...or maybe you'll use the time that you're saving to start flossing more often. 😬

+
+## Getting Started
+
+### Prerequisites
+
+- A Unix-like operating system: macOS, Linux, BSD. On Windows: WSL2 is preferred, but cygwin or msys also mostly work.
+- [Zsh](https://www.zsh.org) should be installed (v4.3.9 or more recent is fine but we prefer 5.0.8 and newer). If not pre-installed (run `zsh --version` to confirm), check the following wiki instructions here: [Installing ZSH](https://github.com/ohmyzsh/ohmyzsh/wiki/Installing-ZSH)
+- `curl` or `wget` should be installed
+- `git` should be installed (recommended v2.4.11 or higher)
+
+### Basic Installation
+
+Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either `curl`, `wget` or another similar tool.
+
+| Method    | Command                                                                                           |
+| :-------- | :------------------------------------------------------------------------------------------------ |
+| **curl**  | `sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"` |
+| **wget**  | `sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"`   |
+| **fetch** | `sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"` |
+
+_Note that any previous `.zshrc` will be renamed to `.zshrc.pre-oh-my-zsh`. After installation, you can move the configuration you want to preserve into the new `.zshrc`._
+
+#### Manual inspection
+
+It's a good idea to inspect the install script from projects you don't yet know. You can do
+that by downloading the install script first, looking through it so everything looks normal,
+then running it:
+
+```sh
+wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
+sh install.sh
+```
+
+## Using Oh My Zsh
+
+### Plugins
+
+Oh My Zsh comes with a shitload of plugins for you to take advantage of. You can take a look in the [plugins](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins) directory and/or the [wiki](https://github.com/ohmyzsh/ohmyzsh/wiki/Plugins) to see what's currently available.
+
+#### Enabling Plugins
+
+Once you spot a plugin (or several) that you'd like to use with Oh My Zsh, you'll need to enable them in the `.zshrc` file. You'll find the zshrc file in your `$HOME` directory. Open it with your favorite text editor and you'll see a spot to list all the plugins you want to load.
+
+```sh
+vi ~/.zshrc
+```
+
+For example, this might begin to look like this:
+
+```sh
+plugins=(
+  git
+  bundler
+  dotenv
+  macos
+  rake
+  rbenv
+  ruby
+)
+```
+
+_Note that the plugins are separated by whitespace (spaces, tabs, new lines...). **Do not** use commas between them or it will break._
+
+#### Using Plugins
+
+Each built-in plugin includes a **README**, documenting it. This README should show the aliases (if the plugin adds any) and extra goodies that are included in that particular plugin.
+
+### Themes
+
+We'll admit it. Early in the Oh My Zsh world, we may have gotten a bit too theme happy. We have over one hundred and fifty themes now bundled. Most of them have [screenshots](https://github.com/ohmyzsh/ohmyzsh/wiki/Themes) on the wiki (We are working on updating this!). Check them out!
+
+#### Selecting a Theme
+
+_Robby's theme is the default one. It's not the fanciest one. It's not the simplest one. It's just the right one (for him)._
+
+Once you find a theme that you'd like to use, you will need to edit the `~/.zshrc` file. You'll see an environment variable (all caps) in there that looks like:
+
+```sh
+ZSH_THEME="robbyrussell"
+```
+
+To use a different theme, simply change the value to match the name of your desired theme. For example:
+
+```sh
+ZSH_THEME="agnoster" # (this is one of the fancy ones)
+# see https://github.com/ohmyzsh/ohmyzsh/wiki/Themes#agnoster
+```
+
+_Note: many themes require installing a [Powerline Font](https://github.com/powerline/fonts) or a [Nerd Font](https://github.com/ryanoasis/nerd-fonts) in order to render properly. Without them, these themes will render [weird prompt symbols](https://github.com/ohmyzsh/ohmyzsh/wiki/FAQ#i-have-a-weird-character-in-my-prompt)_
+
+Open up a new terminal window and your prompt should look something like this:
+
+![Agnoster theme](https://cloud.githubusercontent.com/assets/2618447/6316862/70f58fb6-ba03-11e4-82c9-c083bf9a6574.png)
+
+In case you did not find a suitable theme for your needs, please have a look at the wiki for [more of them](https://github.com/ohmyzsh/ohmyzsh/wiki/External-themes).
+
+If you're feeling feisty, you can let the computer select one randomly for you each time you open a new terminal window.
+
+```sh
+ZSH_THEME="random" # (...please let it be pie... please be some pie..)
+```
+
+And if you want to pick random theme from a list of your favorite themes:
+
+```sh
+ZSH_THEME_RANDOM_CANDIDATES=(
+  "robbyrussell"
+  "agnoster"
+)
+```
+
+If you only know which themes you don't like, you can add them similarly to an ignored list:
+
+```sh
+ZSH_THEME_RANDOM_IGNORED=(pygmalion tjkirch_mod)
+```
+
+### FAQ
+
+If you have some more questions or issues, you might find a solution in our [FAQ](https://github.com/ohmyzsh/ohmyzsh/wiki/FAQ).
+
+## Advanced Topics
+
+If you're the type that likes to get their hands dirty, these sections might resonate.
+
+### Advanced Installation
+
+Some users may want to manually install Oh My Zsh, or change the default path or other settings that
+the installer accepts (these settings are also documented at the top of the install script).
+
+#### Custom Directory
+
+The default location is `~/.oh-my-zsh` (hidden in your home directory, you can access it with `cd ~/.oh-my-zsh`)
+
+If you'd like to change the install directory with the `ZSH` environment variable, either by running
+`export ZSH=/your/path` before installing, or by setting it before the end of the install pipeline
+like this:
+
+```sh
+ZSH="$HOME/.dotfiles/oh-my-zsh" sh install.sh
+```
+
+#### Unattended install
+
+If you're running the Oh My Zsh install script as part of an automated install, you can pass the `--unattended`
+flag to the `install.sh` script. This will have the effect of not trying to change
+the default shell, and it also won't run `zsh` when the installation has finished.
+
+```sh
+sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended
+```
+
+#### Installing from a forked repository
+
+The install script also accepts these variables to allow installation of a different repository:
+
+- `REPO` (default: `ohmyzsh/ohmyzsh`): this takes the form of `owner/repository`. If you set
+  this variable, the installer will look for a repository at `https://github.com/{owner}/{repository}`.
+
+- `REMOTE` (default: `https://github.com/${REPO}.git`): this is the full URL of the git repository
+  clone. You can use this setting if you want to install from a fork that is not on GitHub (GitLab,
+  Bitbucket...) or if you want to clone with SSH instead of HTTPS (`git@github.com:user/project.git`).
+
+  _NOTE: it's incompatible with setting the `REPO` variable. This setting will take precedence._
+
+- `BRANCH` (default: `master`): you can use this setting if you want to change the default branch to be
+  checked out when cloning the repository. This might be useful for testing a Pull Request, or if you
+  want to use a branch other than `master`.
+
+For example:
+
+```sh
+REPO=apjanke/oh-my-zsh BRANCH=edge sh install.sh
+```
+
+#### Manual Installation
+
+##### 1. Clone the repository <!-- omit in toc -->
+
+```sh
+git clone https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh
+```
+
+##### 2. _Optionally_, backup your existing `~/.zshrc` file <!-- omit in toc -->
+
+```sh
+cp ~/.zshrc ~/.zshrc.orig
+```
+
+##### 3. Create a new zsh configuration file <!-- omit in toc -->
+
+You can create a new zsh config file by copying the template that we have included for you.
+
+```sh
+cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
+```
+
+##### 4. Change your default shell <!-- omit in toc -->
+
+```sh
+chsh -s $(which zsh)
+```
+
+You must log out from your user session and log back in to see this change.
+
+##### 5. Initialize your new zsh configuration <!-- omit in toc -->
+
+Once you open up a new terminal window, it should load zsh with Oh My Zsh's configuration.
+
+### Installation Problems
+
+If you have any hiccups installing, here are a few common fixes.
+
+- You _might_ need to modify your `PATH` in `~/.zshrc` if you're not able to find some commands after switching to `oh-my-zsh`.
+- If you installed manually or changed the install location, check the `ZSH` environment variable in `~/.zshrc`.
+
+### Custom Plugins and Themes
+
+If you want to override any of the default behaviors, just add a new file (ending in `.zsh`) in the `custom/` directory.
+
+If you have many functions that go well together, you can put them as a `XYZ.plugin.zsh` file in the `custom/plugins/` directory and then enable this plugin.
+
+If you would like to override the functionality of a plugin distributed with Oh My Zsh, create a plugin of the same name in the `custom/plugins/` directory and it will be loaded instead of the one in `plugins/`.
+
+### Enable GNU ls in macOS and freeBSD systems
+
+<a name="enable-gnu-ls"></a>
+
+The default behaviour in Oh My Zsh is to use BSD `ls` in macOS and freeBSD systems. If GNU `ls` is installed
+(as `gls` command), you can choose to use it instead. To do it, you can use zstyle-based config before
+sourcing `oh-my-zsh.sh`:
+
+```zsh
+zstyle ':omz:lib:theme-and-appearance' gnu-ls yes
+```
+
+_Note: this is not compatible with `DISABLE_LS_COLORS=true`_
+
+### Skip aliases
+
+<a name="remove-directories-aliases"></a>
+
+If you want to skip default Oh My Zsh aliases (those defined in `lib/*` files) or plugin aliases,
+you can use the settings below in your `~/.zshrc` file, **before Oh My Zsh is loaded**. Note that
+there are many different ways to skip aliases, depending on your needs.
+
+```sh
+# Skip all aliases, in lib files and enabled plugins
+zstyle ':omz:*' aliases no
+
+# Skip all aliases in lib files
+zstyle ':omz:lib:*' aliases no
+# Skip only aliases defined in the directories.zsh lib file
+zstyle ':omz:lib:directories' aliases no
+
+# Skip all plugin aliases
+zstyle ':omz:plugins:*' aliases no
+# Skip only the aliases from the git plugin
+zstyle ':omz:plugins:git' aliases no
+```
+
+You can combine these in other ways taking into account that more specific scopes takes precedence:
+
+```sh
+# Skip all plugin aliases, except for the git plugin
+zstyle ':omz:plugins:*' aliases no
+zstyle ':omz:plugins:git' aliases yes
+```
+
+A previous version of this feature was using the setting below, which has been removed:
+
+```sh
+zstyle ':omz:directories' aliases no
+```
+
+Instead, you can now use the following:
+
+```sh
+zstyle ':omz:lib:directories' aliases no
+```
+
+#### Notice <!-- omit in toc -->
+
+> This feature is currently in a testing phase and it may be subject to change in the future.
+> It is also not currently compatible with plugin managers such as zpm or zinit, which don't
+> source the init script (`oh-my-zsh.sh`) where this feature is implemented in.
+
+> It is also not currently aware of "aliases" that are defined as functions. Example of such
+> are `gccd`, `ggf`, or `ggl` functions from the git plugin.
+
+## Getting Updates
+
+By default, you will be prompted to check for updates every 2 weeks. You can choose other update modes by adding a line to your `~/.zshrc` file, **before Oh My Zsh is loaded**:
+
+1. Automatic update without confirmation prompt:
+
+   ```sh
+   zstyle ':omz:update' mode auto
+   ```
+
+2. Just offer a reminder every few days, if there are updates available:
+
+   ```sh
+   zstyle ':omz:update' mode reminder
+   ```
+
+3. To disable automatic updates entirely:
+
+   ```sh
+   zstyle ':omz:update' mode disabled
+   ```
+
+NOTE: you can control how often Oh My Zsh checks for updates with the following setting:
+
+```sh
+# This will check for updates every 7 days
+zstyle ':omz:update' frequency 7
+# This will check for updates every time you open the terminal (not recommended)
+zstyle ':omz:update' frequency 0
+```
+
+### Updates verbosity
+
+You can also limit the update verbosity with the following settings:
+
+```sh
+zstyle ':omz:update' verbose default # default update prompt
+
+zstyle ':omz:update' verbose minimal # only few lines
+
+zstyle ':omz:update' verbose silent # only errors
+```
+
+### Manual Updates
+
+If you'd like to update at any point in time (maybe someone just released a new plugin and you don't want to wait a week?) you just need to run:
+
+```sh
+omz update
+```
+
+Magic! 🎉
+
+## Uninstalling Oh My Zsh
+
+Oh My Zsh isn't for everyone. We'll miss you, but we want to make this an easy breakup.
+
+If you want to uninstall `oh-my-zsh`, just run `uninstall_oh_my_zsh` from the command-line. It will remove itself and revert your previous `bash` or `zsh` configuration.

+
+This sample hook safeguards topic branches that have been
+published from being rewound.
+
+The workflow assumed here is:
+
+ * Once a topic branch forks from "master", "master" is never
+   merged into it again (either directly or indirectly).
+
+ * Once a topic branch is fully cooked and merged into "master",
+   it is deleted.  If you need to build on top of it to correct
+   earlier mistakes, a new topic branch is created by forking at
+   the tip of the "master".  This is not strictly necessary, but
+   it makes it easier to keep your history simple.
+
+ * Whenever you need to test or publish your changes to topic
+   branches, merge them into "next" branch.
+
+The script, being an example, hardcodes the publish branch name
+to be "next", but it is trivial to make it configurable via
+$GIT_DIR/config mechanism.
+
+With this workflow, you would want to know:
+
+(1) ... if a topic branch has ever been merged to "next".  Young
+    topic branches can have stupid mistakes you would rather
+    clean up before publishing, and things that have not been
+    merged into other branches can be easily rebased without
+    affecting other people.  But once it is published, you would
+    not want to rewind it.
+
+(2) ... if a topic branch has been fully merged to "master".
+    Then you can delete it.  More importantly, you should not
+    build on top of it -- other people may already want to
+    change things related to the topic as patches against your
+    "master", so if you need further changes, it is better to
+    fork the topic (perhaps with the same name) afresh from the
+    tip of "master".
+
+Let's look at this example:

+ * A has one fix since it was merged up to "next".
+
+ * B has finished.  It has been fully merged up to "master" and "next",
+   and is ready to be deleted.

+
+To compute (2):

+# This hook is invoked by git-receive-pack(1) when it reacts to git
+# push and updates reference(s) in its repository, and when the push
+# tries to update the branch that is currently checked out and the
+# receive.denyCurrentBranch configuration variable is set to
+# updateInstead.
+#
+# By default, such a push is refused if the working tree and the index

+# checked out commit; when both the working tree and the index match
+# the current commit, they are updated to match the newly pushed tip
+# of the branch. This hook is to be used to override the default
+# behaviour; however the code below reimplements the default behaviour
+# as a starting point for convenient modification.
+#
+# The hook receives the commit with which the tip of the current
+# branch is going to be updated:
+commit=$1
+
+# It can exit with a non-zero status to refuse the push (when it does
+# so, it must not modify the index or the working tree).

+# in order to emulate git fetch that is run in the reverse direction
+# with git push, as the two-tree form of git read-tree -u -m is
+# essentially the same as git switch or git checkout that switches
+# branches while keeping the local changes in the working tree that do
+# not interfere with the difference between the branches.
+
+# The below is a more-or-less exact translation to shell of the C code
+# for the default behaviour for git's push-to-checkout hook defined in
+# the push_to_deploy() function in builtin/receive-pack.c.
+#
+# Note that the hook will be executed from the repository directory,

+# Recommended font: Meslo Nerd Font patched for Powerlevel10k
+
+Gorgeous monospace font designed by Jim Lyles for Bitstream, customized by the same for Apple,
+further customized by André Berg, and finally patched by yours truly with customized scripts
+originally developed by Ryan L McIntyre of Nerd Fonts. Contains all glyphs and symbols that
+Powerlevel10k may need. Battle-tested in dozens of different terminals on all major operating
+systems.
+
+*FAQ*: [How was the recommended font created?](README.md#how-was-the-recommended-font-created)
+
+## Automatic font installation
+
+If you are using iTerm2 or Termux, `p10k configure` can install the recommended font for you.
+Simply answer `Yes` when asked whether to install *Meslo Nerd Font*.
+
+If you are using a different terminal, proceed with manual font installation. 👇
+
+## Manual font installation
+
+1. Download these four ttf files:
+   - [MesloLGS NF Regular.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Regular.ttf)
+   - [MesloLGS NF Bold.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold.ttf)
+   - [MesloLGS NF Italic.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Italic.ttf)
+   - [MesloLGS NF Bold Italic.ttf](
+       https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold%20Italic.ttf)
+1. Double-click on each file and click "Install". This will make `MesloLGS NF` font available to all
+   applications on your system.
+1. Configure your terminal to use this font:
+   - **iTerm2**: Type `p10k configure` and answer `Yes` when asked whether to install
+     *Meslo Nerd Font*. Alternatively, open *iTerm2 → Preferences → Profiles → Text* and set *Font* to
+     `MesloLGS NF`.
+   - **Apple Terminal**: Open *Terminal → Preferences → Profiles → Text*, click *Change* under *Font*
+     and select `MesloLGS NF` family.
+   - **Hyper**: Open *Hyper → Edit → Preferences* and change the value of `fontFamily` under
+     `module.exports.config` to `MesloLGS NF`.
+   - **Visual Studio Code**: Open *File → Preferences → Settings* (PC) or
+     *Code → Preferences → Settings* (Mac), enter `terminal.integrated.fontFamily` in the search box at
+     the top of *Settings* tab and set the value below to `MesloLGS NF`.
+     Consult [this screenshot](
+       https://raw.githubusercontent.com/romkatv/powerlevel10k-media/389133fb8c9a2347929a23702ce3039aacc46c3d/visual-studio-code-font-settings.jpg)
+     to see how it should look like or see [this issue](
+       https://github.com/romkatv/powerlevel10k/issues/671) for extra information.
+   - **GNOME Terminal** (the default Ubuntu terminal): Open *Terminal → Preferences* and click on the
+     selected profile under *Profiles*. Check *Custom font* under *Text Appearance* and select
+     `MesloLGS NF Regular`.

+     *Properties → Font* and set *Font* to `MesloLGS NF`.
+   - **Windows Terminal** by Microsoft (the new thing): Open *Settings* (<kbd>Ctrl+,</kbd>), click
+     either on the selected profile under *Profiles* or on *Defaults*, click *Appearance* and set
+     *Font face* to `MesloLGS NF`.
+   - **IntelliJ** (and other IDEs by Jet Brains): Open *IDE → Edit → Preferences → Editor →
+     Color Scheme → Console Font*. Select *Use console font instead of the default* and set the font
+     name to `MesloLGS NF`.
+   - **Termux**: Type `p10k configure` and answer `Yes` when asked whether to install
+     *Meslo Nerd Font*.
+   - **Blink**: Type `config`, go to *Appearance*, tap *Add a new font*, tap *Open Gallery*, select
+     *MesloLGS NF.css*, tap *import* and type `exit` in the home view to reload the font.
+   - **Tabby** (formerly **Terminus**): Open *Settings → Appearance* and set *Font* to `MesloLGS NF`.
+   - **Terminator**: Open *Preferences* using the context menu. Under *Profiles* select the *General*
+     tab (should be selected already), uncheck *Use the system fixed width font* (if not already)
+     and select `MesloLGS NF Regular`. Exit the Preferences dialog by clicking *Close*.
+   - **Guake**: Right Click on an open terminal and open *Preferences*. Under *Appearance*

+     local wezterm = require 'wezterm';
+     return {
+         font = wezterm.font("MesloLGS NF"),
+     }
+     ```
+     If the file already exists, only add the line with the font to the existing return.
+     Also add the first line if it is not already present.

+     ```
+     You can adjust the font size to your preference. After changing the config run
+     `xrdb ~/.Xresources` to reload it. The new config is applied to all new terminals.
+   - **xterm**: Create or open `~/.Xresources` and add the following line to it:
+     ```text
+     xterm*faceName: MesloLGS NF
+     ```
+     After changing the config run `xrdb ~/.Xresources` to reload it. The new config is applied to

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see

+# gitstatus
+
+**gitstatus** is a 10x faster alternative to `git status` and `git describe`. Its primary use
+case is to enable fast git prompt in interactive shells.
+
+Heavy lifting is done by **gitstatusd** -- a custom binary written in C++. It comes with Zsh and
+Bash bindings for integration with shell.

+
+## Using from Zsh
+
+The easiest way to take advantage of gitstatus from Zsh is to use a theme that's already integrated
+with it. For example, [Powerlevel10k](https://github.com/romkatv/powerlevel10k) is a flexible and
+fast theme with first-class gitstatus integration. If you install Powerlevel10k, you don't need to
+install gitstatus.
+
+![Powerlevel10k Zsh Theme](
+  https://raw.githubusercontent.com/romkatv/powerlevel10k-media/master/prompt-styles-high-contrast.png)
+
+For those who wish to use gitstatus without a theme, there is
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh). Install it as follows:
+
+```zsh
+git clone --depth=1 https://github.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.zsh' >>! ~/.zshrc
+```
+
+Users in China can use the official mirror on gitee.com for faster download.<br>
+中国大陆用户可以使用 gitee.com 上的官方镜像加速下载.
+
+```zsh
+git clone --depth=1 https://gitee.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.zsh' >>! ~/.zshrc
+```
+
+Alternatively, if you have Homebrew installed:
+
+```zsh
+brew install romkatv/gitstatus/gitstatus
+echo "source $(brew --prefix)/opt/gitstatus/gitstatus.prompt.zsh" >>! ~/.zshrc
+```
+
+(If you choose this option, replace `~/gitstatus` with `$(brew --prefix)/opt/gitstatus/gitstatus`
+in all code snippets below.)
+
+_Make sure to disable your current theme if you have one._
+
+This will give you a basic yet functional prompt with git status in it. It's
+[over 10x faster](#benchmarks) than any alternative that can give you comparable prompt. In order
+to customize it, set `PROMPT` and/or `RPROMPT` at the end of `~/.zshrc` after sourcing
+`gitstatus.prompt.zsh`. Insert `${GITSTATUS_PROMPT}` where you want git status to go. For example:
+
+```zsh
+source ~/gitstatus/gitstatus.prompt.zsh
+
+PROMPT='%~%# '               # left prompt: directory followed by %/# (normal/root)
+RPROMPT='$GITSTATUS_PROMPT'  # right prompt: git status
+```
+
+The expansion of `${GITSTATUS_PROMPT}` can contain the following bits:
+
+| segment     |  meaning                                              |
+|-------------|-------------------------------------------------------|
+| `master`    | current branch                                        |
+| `#v1`       | HEAD is tagged with `v1`; not shown when on a branch  |
+| `@5fc6fca4` | current commit; not shown when on a branch or tag     |
+| `⇣1`        | local branch is behind the remote by 1 commit         |
+| `⇡2`        | local branch is ahead of the remote by 2 commits      |
+| `⇠3`        | local branch is behind the push remote by 3 commits   |
+| `⇢4`        | local branch is ahead of the push remote by 4 commits |
+| `*5`        | there are 5 stashes                                   |
+| `merge`     | merge is in progress (could be some other action)     |
+| `~6`        | there are 6 merge conflicts                           |
+| `+7`        | there are 7 staged changes                            |
+| `!8`        | there are 8 unstaged changes                          |
+| `?9`        | there are 9 untracked files                           |
+
+`$GITSTATUS_PROMPT_LEN` tells you how long `$GITSTATUS_PROMPT` is when printed to the console.
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh) has an example of using it to truncate the current
+directory.
+
+If you'd like to change the format of git status, or want to have greater control over the
+process of assembling `PROMPT`, you can copy and modify parts of
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh) instead of sourcing the script. Your `~/.zshrc`
+might look something like this:
+
+```zsh
+source ~/gitstatus/gitstatus.plugin.zsh
+
+function my_set_prompt() {
+  PROMPT='%~%# '
+  RPROMPT=''
+
+  if gitstatus_query MY && [[ $VCS_STATUS_RESULT == ok-sync ]]; then
+    RPROMPT=${${VCS_STATUS_LOCAL_BRANCH:-@${VCS_STATUS_COMMIT}}//\%/%%}  # escape %
+    (( VCS_STATUS_NUM_STAGED    )) && RPROMPT+='+'
+    (( VCS_STATUS_NUM_UNSTAGED  )) && RPROMPT+='!'
+    (( VCS_STATUS_NUM_UNTRACKED )) && RPROMPT+='?'
+  fi
+
+  setopt no_prompt_{bang,subst} prompt_percent  # enable/disable correct prompt expansions
+}
+
+gitstatus_stop 'MY' && gitstatus_start -s -1 -u -1 -c -1 -d -1 'MY'
+autoload -Uz add-zsh-hook
+add-zsh-hook precmd my_set_prompt
+```
+
+This snippet is sourcing `gitstatus.plugin.zsh` rather than `gitstatus.prompt.zsh`. The former
+defines low-level bindings that communicate with gitstatusd over pipes. The latter is a simple
+script that uses these bindings to assemble git prompt.
+
+Unlike [Powerlevel10k](https://github.com/romkatv/powerlevel10k), code based on
+[gitstatus.prompt.zsh](gitstatus.prompt.zsh) is communicating with gitstatusd synchronously. This
+can make your prompt slow when working in a large git repository or on a slow machine. To avoid
+this problem, call `gitstatus_query` asynchronously as documented in
+[gitstatus.plugin.zsh](gitstatus.plugin.zsh). This can be quite challenging.
+
+## Using from Bash
+
+The easiest way to take advantage of gitstatus from Bash is via
+[gitstatus.prompt.sh](gitstatus.prompt.sh). Install it as follows:
+
+```bash
+git clone --depth=1 https://github.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.sh' >> ~/.bashrc
+```
+
+Users in China can use the official mirror on gitee.com for faster download.<br>
+中国大陆用户可以使用 gitee.com 上的官方镜像加速下载.
+
+```bash
+git clone --depth=1 https://gitee.com/romkatv/gitstatus.git ~/gitstatus
+echo 'source ~/gitstatus/gitstatus.prompt.sh' >> ~/.bashrc
+```
+
+Alternatively, if you have Homebrew installed:
+
+```zsh
+brew install romkatv/gitstatus/gitstatus
+echo "source $(brew --prefix)/opt/gitstatus/gitstatus.prompt.sh" >> ~/.bashrc
+```
+
+(If you choose this option, replace `~/gitstatus` with `$(brew --prefix)/opt/gitstatus/gitstatus`
+in all code snippets below.)
+
+This will give you a basic yet functional prompt with git status in it. It's
+[over 10x faster](#benchmarks) than any alternative that can give you comparable prompt.
+
+![Bash Prompt with GitStatus](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/bash-prompt.png)
+
+In order to customize your prompt, set `PS1` at the end of `~/.bashrc` after sourcing
+`gitstatus.prompt.sh`. Insert `${GITSTATUS_PROMPT}` where you want git status to go. For example:
+
+```bash
+source ~/gitstatus/gitstatus.prompt.sh
+
+PS1='\w ${GITSTATUS_PROMPT}\n\$ ' # directory followed by git status and $/# (normal/root)
+```
+
+The expansion of `${GITSTATUS_PROMPT}` can contain the following bits:
+
+| segment     |  meaning                                              |
+|-------------|-------------------------------------------------------|
+| `master`    | current branch                                        |
+| `#v1`       | HEAD is tagged with `v1`; not shown when on a branch  |
+| `@5fc6fca4` | current commit; not shown when on a branch or tag     |
+| `⇣1`        | local branch is behind the remote by 1 commit         |

+| `⇠3`        | local branch is behind the push remote by 3 commits   |
+| `⇢4`        | local branch is ahead of the push remote by 4 commits |
+| `*5`        | there are 5 stashes                                   |
+| `merge`     | merge is in progress (could be some other action)     |

+| `!8`        | there are 8 unstaged changes                          |
+| `?9`        | there are 9 untracked files                           |
+
+If you'd like to change the format of git status, or want to have greater control over the
+process of assembling `PS1`, you can copy and modify parts of
+[gitstatus.prompt.sh](gitstatus.prompt.sh) instead of sourcing the script. Your `~/.bashrc` might
+look something like this:
+

+  if gitstatus_query && [[ "$VCS_STATUS_RESULT" == ok-sync ]]; then
+    if [[ -n "$VCS_STATUS_LOCAL_BRANCH" ]]; then
+      PS1+=" ${VCS_STATUS_LOCAL_BRANCH//\\/\\\\}"  # escape backslash
+    else
+      PS1+=" @${VCS_STATUS_COMMIT//\\/\\\\}"       # escape backslash
+    fi
+    (( VCS_STATUS_HAS_STAGED"    )) && PS1+='+'
+    (( VCS_STATUS_HAS_UNSTAGED"  )) && PS1+='!'
+    (( VCS_STATUS_HAS_UNTRACKED" )) && PS1+='?'
+  fi
+
+  PS1+='\n\$ '
+
+  shopt -u promptvars  # disable expansion of '$(...)' and the like
+}
+
+gitstatus_stop && gitstatus_start
+PROMPT_COMMAND=my_set_prompt
+```
+
+This snippet is sourcing `gitstatus.plugin.sh` rather than `gitstatus.prompt.sh`. The former
+defines low-level bindings that communicate with gitstatusd over pipes. The latter is a simple
+script that uses these bindings to assemble git prompt.
+
+Note: Bash bindings, unlike Zsh bindings, don't support asynchronous calls.
+
+## Using from other shells
+
+If there are no gitstatusd bindings for your shell, you'll need to get your hands dirty.
+Use the existing bindings for inspiration; run `gitstatusd --help` or read the same thing in
+[options.cc](src/options.cc).
+
+## How it works
+
+gitstatusd reads requests from stdin and prints responses to stdout. Requests contain an ID and
+a directory. Responses contain the same ID and machine-readable git status for the directory.
+gitstatusd keeps some state in memory for the directories it has seen in order to serve future
+requests faster.
+
+[Zsh bindings](gitstatus.plugin.zsh) and [Bash bindings](gitstatus.plugin.sh) start gitstatusd in
+the background and communicate with it via pipes. Themes such as
+[Powerlevel10k](https://github.com/romkatv/powerlevel10k) use these bindings to put git status in
+`PROMPT`.
+
+Note that gitstatus cannot be used as a drop-in replacement for `git status` command as it doesn't
+produce output in the same format. It does perform the same computation though.
+
+## Benchmarks
+
+The following benchmark results were obtained on Intel i9-7900X running Ubuntu 18.04 in
+a clean [chromium](https://github.com/chromium/chromium) repository synced to `9394e49a`. The
+repository was checked out to an ext4 filesystem on M.2 SSD.
+
+Three functionally equivalent tools for computing git status were benchmarked:
+
+* `gitstatusd`
+* `git` with untracked cache enabled
+* `lg2` -- a demo/example executable from [libgit2](https://github.com/romkatv/libgit2) that
+  implements a subset of `git` functionality on top of libgit2 API; for the purposes of this
+  benchmark the subset is sufficient to generate the same data as the other tools
+
+Every tool was benchmark in cold and hot conditions. For `git` the first run in a repository was
+considered cold, with the following runs considered hot. `lg2` was patched to compute results twice
+in a single invocation without freeing the repository in between; the second run was considered hot.
+The same patching was not done for `git` because `git` cannot be easily modified to refresh inmemory
+index state between invocations; in fact, this limitation is one of the primary reasons developers
+use libgit2. `gitstatusd` was benchmarked similarly to `lg2` with two result computations in the
+same invocation.
+
+Two commands were benchmarked: `status` and `describe`.
+
+### Status
+
+In this benchmark all tools were computing the equivalent of `git status`. Lower numbers are better.
+
+| Tool          |      Cold  |         Hot |
+|---------------|-----------:|------------:|
+| **gitstatus** | **291 ms** | **30.9 ms** |
+| git           |     876 ms |      295 ms |
+| lg2           |    1730 ms |     1310 ms |
+
+gitstatusd is substantially faster than the alternatives, especially on hot runs. Note that hot runs
+are of primary importance to the main use case of gitstatus in interactive shells.
+
+The performance of `git status` fluctuated wildly in this benchmarks for reasons unknown to the
+author. Moreover, performance is sticky -- once `git status` settles around a number, it stays
+there for a long time. Numbers as diverse as 295, 352, 663 and 730 had been observed on hot runs on
+the same repository. The number in the table is the lowest (fastest or best) that `git status` had
+shown.
+
+### Describe
+
+In this benchmark all tools were computing the equivalent of `git describe --tags --exact-match`
+to find tags that resolve to the same commit as `HEAD`. Lower numbers are better.
+
+| Tool          |       Cold  |           Hot |
+|---------------|------------:|--------------:|
+| **gitstatus** | **4.04 ms** | **0.0345 ms** |
+| git           |     18.0 ms |       14.5 ms |
+| lg2           |      185 ms |       45.2 ms |
+
+gitstatusd is once again faster than the alternatives, more so on hot runs.
+
+## Why fast
+
+Since gitstatusd doesn't have to print all staged/unstaged/untracked files but only report
+whether there are any, it can terminate repository scan early. It can also remember which files
+were dirty on the previous run and check them first on the next run to avoid the scan entirely if
+the files are still dirty. However, the benchmarks above were performed in a clean repository where
+these shortcuts do not trigger. All benchmarked tools had to do the same work -- check the status
+of every file in the index to see if it has changed, check every directory for newly created files,
+etc. And yet, gitstatusd came ahead by a large margin. This section describes what it does that
+makes it so fast.
+
+Most of the following comparisons are done against libgit2 rather than git because of the author's
+familiarity with the former but not the with latter. libgit2 has clean, well-documented APIs and an
+elegant implementation, which makes it so much easier to work with and to analyze performance
+bottlenecks.
+
+### Summary for the impatient
+
+Under the benchmark conditions described above, the equivalent of libgit2's
+`git_diff_index_to_workdir` (the most expensive part of `status` command) is 46.3 times faster in
+gitstatusd. The speedup comes from the following sources.
+
+* gitstatusd uses more efficient data structures and algorithms and employs performance-conscious
+coding style throughout the codebase. This reduces CPU time in userspace by 32x compared to libgit2.
+* gitstatusd uses less expensive system calls and makes fewer of them. This reduces CPU time spent
+in kernel by 1.9x.
+* gitstatusd can utilize multiple cores to scan index and workdir in parallel with almost perfect
+scaling. This reduces total run time by 12.4x while having virtually no effect on total CPU time.
+
+### Problem statement
+
+The most resource-intensive part of the `status` command is finding the difference between _index_
+and _workdir_ (`git_diff_index_to_workdir` in libgit2). Index is a list of all files in the git
+repository with their last modification times. This is an obvious simplification but it suffices for
+this exposition. On disk, index is stored sorted by file path. Here's an example of git index:
+
+| File        | Last modification time |
+|-------------|-----------------------:|
+| Makefile    |   2019-04-01T14:12:32Z |
+| src/hello.c |   2019-04-01T14:12:00Z |
+| src/hello.h |   2019-04-01T14:12:32Z |
+
+This list needs to be compared to the list of files in the working directory. If any of the files
+listed in the index are missing from the workdir or have different last modification time, they are
+"unstaged" in gitstatusd parlance. If you run `git status`, they'll be shown as "changes not staged
+for commit". Thus, any implementation of `status` command has to call `stat()` or one of its
+variants on every file in the index.
+
+In addition, all files in the working directory for which there is no entry in the index at all are
+"untracked". `git status` will show them as "untracked files". Finding untracked files requires some
+form of work directory traversal.
+
+### Single-threaded scan
+
+Let's see how `git_diff_index_to_workdir` from libgit2 accomplishes these tasks. Here's its CPU
+profile from 200 hot runs over chromium repository.
+
+![libgit2 CPU profile (hot)](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/cpu-profile-libgit2.png)
+
+(The CPU profile was created with [gperftools](https://github.com/gperftools/gperftools) and
+rendered with [pprof](https://github.com/google/pprof)).
+
+We can see `__GI__lxstat` taking a lot of time. This is the `stat()` call for every file in the
+index. We can also identify `__opendir`, `__readdir` and `__GI___close_nocancel` -- glibc wrappers
+for reading the contents of a directory. This is for finding untracked files. Out of the total 232
+seconds, 111 seconds -- or 47.7% -- was spent on these calls. The rest is computation -- comparing
+strings, sorting arrays, etc.
+
+Now let's take a look at the CPU profile of gitstatusd on the same task.
+
+![gitstatusd CPU profile (hot)](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/cpu-profile-gitstatusd-hot.png)
+
+The first impression is that this profile looks pruned. This isn't an artifact. The profile was
+generated with the same tools and the same flags as the profile of libgit2.
+
+Since both profiles were generated from the same workload, absolute numbers can be compared. We can
+see that gitstatusd took 62 seconds in total compared to libgit2's 232 seconds. System calls at the
+core of the algorithm are cleary visible. `__GI___fxstatat` is a flavor of `stat()`, and the other
+three calls -- `__libc_openat64`, `__libc_close` and `__GI___fxstat` are responsible for opening
+directories and finding untracked files. Notice that there is almost nothing else in the profile
+apart from these calls. The rest of the code accounts for 3.77 seconds of CPU time -- 32 times less
+than in libgit2.
+
+So, one reason gitstatusd is fast is that it has efficient diffing code -- very little time is spent
+outside of kernel. However, if we look closely, we can notice that system calls in gitstatusd are
+_also_ faster than in libgit2. For example, libgit2 spent 72.07 seconds in `__GI__lxstat` while
+gitstatusd spent only 48.82 seconds in `__GI___fxstatat`. There are two reasons for this difference.
+First, libgit2 makes more `stat()` calls than is strictly required. It's not necessary to stat
+directories because index only has files. There are 25k directories in chromium repository (and 300k
+files) -- that's 25k `stat()` calls that could be avoided. The second reason is that libgit2 and
+gitstatusd use different flavors of `stat()`. libgit2 uses `lstat()`, which takes a path to the file
+as input. Its performance is linear in the number of subdirectories in the path because it needs to
+perform a lookup for every one of them and to check permissions. gitstatusd uses `fstatat()`, which
+takes a file descriptor to the parent directory and a name of the file. Just a single lookup, less
+CPU time.
+
+Similarly to `lstat()` vs `fstatat()`, it's faster to open files and directories with `openat()`
+from the parent directory file descriptor than with regular `open()` that accepts full file path.
+gitstatusd takes advantage of `openat()` to open directories as fast as possible. It opens about 90%
+of the directories (this depends on the actual directory structure of the repository) from the
+immediate parent -- the most efficient way -- and the remaining 10% it opens from the repository's
+root directory. The reason it's done this way is to keep the maximum number of simultaneously open
+file descriptors bounded. libgit2 can have O(repository depth) simultaneously open file descriptors,
+which may be OK for a single-threaded application but can balloon to a large number when scans are
+done by many threads simultaneously, like in gitstatusd.
+
+There is no equivalent to `__opendir` or `__readdir` in the gitstatusd profile because it uses the
+equivalent of [untracked cache](https://git-scm.com/docs/git-update-index#_untracked_cache) from
+git. On the first scan of the workdir gitstatusd lists all files just like libgit2. But, unlike
+libgit2, it remembers the last modification time of every directory along with the list of
+untracked files under it. On the next scan, gitstatusd can skip listing files in directories whose
+last modification time hasn't changed.
+
+To summarize, here's what gitstatusd was doing when the CPU profile was captured:
+
+1. `__libc_openat64`: Open every directory for which there are files in the index.
+2. `__GI___fxstat`: Check last modification time of the directory. Since it's the same as on the
+   last scan, this directory has the same list of untracked files as before, which is empty (the
+   repository is clean).
+3. `__GI___fxstatat`: Check last modification time for every file in the index that belongs to this
+   directory.
+4. `__libc_close`: Close the file descriptor to the directory.
+
+Here's how the very first scan of a repository looks like in gitstatusd:
+
+![gitstatusd CPU profile (cold)](
+  https://raw.githubusercontent.com/romkatv/gitstatus/1ac366952366d89980b3f3484f270b4fa5ae4293/cpu-profile-gitstatusd-cold.png)
+
+(Some glibc functions are mislabel on this profile. `explicit_bzero` and `__nss_passwd_lookup` are
+in reality `strcmp` and `memcmp`.)
+
+This is a superset of the previous -- hot -- profile, with an extra `syscall` and string sorting for
+directory listing. gitstatusd uses `getdents64` Linux system call directly, bypassing the glibc
+wrapper that libgit2 uses. This is 23% faster. The details of this optimization can be found in a
+[separate document](docs/listdir.md).
+
+### Multithreading
+
+The diffing algorithm in gitstatusd was designed from the ground up with the intention of using it
+concurrently from multiple threads. With a fast SSD, `status` is CPU bound, so taking advantage of
+all available CPU cores is an obvious way to yield results faster.
+
+gitstatusd exhibits almost perfect scaling from multithreading. Engaging all cores allows it to
+produce results 12.4 times faster than in single-threaded execution. This is on Intel i9-7900X with
+10 cores (20 with hyperthreading) with single-core frequency of 4.3GHz and all-core frequency of
+4.0GHz.
+
+Note: `git status` also uses all available cores in some parts of its algorithm while `lg2` does
+everything in a single thread.
+
+### Postprocessing
+
+Once the difference between the index and the workdir is found, we have a list of _candidates_ --
+files that may be unstaged or untracked. To make the final judgement, these files need to be checked
+against `.gitignore` rules and a few other things.
+
+gitstatusd uses [patched libgit2](https://github.com/romkatv/libgit2) for this step. This fork
+adds several optimizations that make libgit2 faster. The patched libgit2 performs more than twice
+as fast in the benchmark as the original even without changes in the user code (that is, in the
+code that uses the libgit2 APIs). The fork also adds several API extensions, most notable of which
+is the support for multi-threaded scans. If `lg2 status` is modified to take advantage of these
+extensions, it outperforms the original libgit2 by a factor of 18. Lastly, the fork fixes a score of
+bugs, most of which become apparent only when using libgit2 from multiple threads.
+
+_WARNING: Changes to libgit2 are extensive but the testing they underwent isn't. It is
+**not recommended** to use the patched libgit2 in production._

+# Fast directory listing
+
+In order to find untracked files in a git repository, [gitstatusd](../README.md) needs to list the
+contents of every directory. gitstatusd does it 27% faster than a reasonable implementation that a
+seasoned C/C++ practitioner might write. This document explains the optimizations that went into it.
+As directory listing is a common operation, many other projects can benefit from applying these
+optimizations.
+
+## v1
+
+Given a path to a directory, `ListDir()` must produce the list of files in that directory. Moreover,
+the list must be sorted lexicographically to enable fast comparison with Git index.
+
+The following C++ implementation gets the job done. For simplicity, it returns an empty list on
+error.
+
+```c++
+vector<string> ListDir(const char* dirname) {
+  vector<string> entries;
+  if (DIR* dir = opendir(dirname)) {
+    while (struct dirent* ent = (errno = 0, readdir(dir))) {
+      if (!Dots(ent->d_name)) entries.push_back(ent->d_name);
+    }
+    if (errno) entries.clear();
+    sort(entries.begin(), entries.end());
+    closedir(dir);
+  }
+  return entries;
+}
+```
+
+Every directory has entries `"."` and `".."`, which we aren't interested in. We filter them out with
+a helper function `Dots()`.
+
+```c++
+bool Dots(const char* s) { return s[0] == '.' && (!s[1] || (s[1] == '.' && !s[2])); }
+```
+
+To check how fast `ListDir()` performs, we can run it many times on a typical directory. One million
+runs on a directory with 32 files with 16-character names takes 12.7 seconds.
+
+## v2
+
+Experienced C++ practitioners will scoff at our implementation of `ListDir()`. If it's meant to be
+efficient, returning `vector<string>` is an unaffordable convenience. To avoid heap allocations we
+can use a simple arena that will allow us to reuse memory between different `ListDir()` calls.
+
+(Changed and added lines are marked with comments.)
+
+```c++
+void ListDir(const char* dirname, string& arena, vector<char*>& entries) {  // +
+  entries.clear();                                                          // +
+  if (DIR* dir = opendir(dirname)) {
+    arena.clear();                                                          // +
+    while (struct dirent* ent = (errno = 0, readdir(dir))) {
+      if (!Dots(ent->d_name)) {
+        entries.push_back(reinterpret_cast<char*>(arena.size()));           // +
+        arena.append(ent->d_name, strlen(ent->d_name) + 1);                 // +
+      }
+    }
+    if (errno) entries.clear();
+    for (char*& p : entries) p = &arena[reinterpret_cast<size_t>(p)];      // +
+    sort(entries.begin(), entries.end(),                                   // +
+         [](const char* a, const char* b) { return strcmp(a, b) < 0; });   // +
+    closedir(dir);
+  }
+}
+```
+
+To make performance comparison easier, we can normalize them relative to the baseline. v1 will get
+performance score of 100. A twice-as-fast alternative will be 200.
+
+| version |     optimization           |     score |
+|---------|----------------------------|----------:|
+| v1      | baseline                   |     100.0 |
+| **v2**  | **avoid heap allocations** | **112.7** |
+
+Avoiding heap allocations makes `ListDir()` 12.7% faster. Not bad. As an added bonus, those casts
+will fend off the occasional frontend developer who accidentally wanders into the codebase.
+
+## v3
+
+`opendir()` is an expensive call whose performance is linear in the number of subdirectories in the
+path because it needs to perform a lookup for every one of them. We can replace it with `openat()`,
+which takes a file descriptor to the parent directory and a name of the subdirectory. Just a single
+lookup, less CPU time. This optimization assumes that callers already have a descriptor to the
+parent directory, which is indeed the case for gitstatusd, and is often the case in other
+applications that traverse filesystem.
+
+```c++
+void ListDir(int parent_fd, const char* dirname, string& arena, vector<char*>& entries) {   // +
+  entries.clear();
+  int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC);  // +
+  if (dir_fd < 0) return;                                                                   // +
+  if (DIR* dir = fdopendir(dir_fd)) {
+    arena.clear();
+    while (struct dirent* ent = (errno = 0, readdir(dir))) {
+      if (!Dots(ent->d_name)) {
+        entries.push_back(reinterpret_cast<char*>(arena.size()));
+        arena.append(ent->d_name, strlen(ent->d_name) + 1);
+      }
+    }
+    if (errno) entries.clear();
+    for (char*& p : entries) p = &arena[reinterpret_cast<size_t>(p)];
+    sort(entries.begin(), entries.end(),
+         [](const char* a, const char* b) { return strcmp(a, b) < 0; });
+    closedir(dir);
+  } else {                                                                                  // +
+    close(dir_fd);                                                                          // +
+  }                                                                                         // +
+}
+```
+
+This is worth about 3.5% in speed.

+
+## v4
+
+Copying file names to the arena isn't free but it doesn't seem like we can avoid it. Poking around
+we can see that the POSIX API we are using is implemented on Linux on top of `getdents64` system
+call. Its documentation isn't very encouraging:
+
+```text
+These are not the interfaces you are interested in.  Look at
+readdir(3) for the POSIX-conforming C library interface.  This page
+documents the bare kernel system call interfaces.
+
+Note: There are no glibc wrappers for these system calls.
+```
+
+Hmm... The API looks like something we can take advantage of, so let's try it anyway.
+
+First, we'll need a simple `Arena` class that can allocate 8KB blocks of memory.
+
+```c++
+class Arena {
+ public:
+  enum { kBlockSize = 8 << 10 };
+
+  char* Alloc() {
+    if (cur_ == blocks_.size()) blocks_.emplace_back(kBlockSize, 0);
+    return blocks_[cur_++].data();
+  }
+
+  void Clear() { cur_ = 0; }
+
+ private:
+  size_t cur_ = 0;
+  vector<string> blocks_;
+};
+```
+
+Next, we need to define `struct dirent64_t` ourselves because there is no wrapper for the system
+call we are about to use.
+
+```c++
+struct dirent64_t {
+  ino64_t d_ino;
+  off64_t d_off;
+  unsigned short d_reclen;
+  unsigned char d_type;
+  char d_name[];
+};
+```
+
+Finally we can get to the implementation of `ListDir()`.
+
+```c++
+void ListDir(int parent_fd, Arena& arena, vector<char*>& entries) {                       // +
+  entries.clear();
+  int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC);
+  if (dir_fd < 0) return;
+  arena.Clear();                                                                          // +
+  while (true) {                                                                          // +
+    char* buf = arena.Alloc();                                                            // +
+    int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize);                      // +
+    if (n <= 0) {                                                                         // +
+      if (n) entries.clear();                                                             // +

+How are we doing with this one?

+| version | optimization                     |     score |
+|---------|----------------------------------|----------:|
+| v1      | baseline                         |     100.0 |
+| v2      | avoid heap allocations           |     112.7 |
+| v3      | open directories with `openat()` |     116.2 |
+| **v4**  | **call `getdents64()` directly** | **137.8** |
+
+Solid 20% speedup. Worth the trouble. Unfortunately, we now have just one `reinterpret_cast` instead
+of two, and it's not nearly as scary-looking. Hopefully with the next iteration we can get back some
+of that evil vibe of low-level code.
+
+As a bonus, every element in `entries` has `d_type` at offset -1. This can be useful to the callers
+that need to distinguish between regular files and directories (gitstatusd, in fact, needs this).
+Note how `ListDir()` implements this feature at zero cost, as a lucky accident of `dirent64_t`
+memory layout.
+
+## v5
+
+The CPU profile of `ListDir()` reveals that almost all userspace CPU time is spent in `strcmp()`.
+Digging into the source code of `std::sort()` we can see that it uses Insertion Sort for short
+collections. Our 32-element vector falls under the threshold. Insertion Sort makes `O(N^2)`
+comparisons, hence a lot of CPU time in `strcmp()`. Switching to `qsort()` or
+[Timsort](https://en.wikipedia.org/wiki/Timsort) is of no use as all good sorting algorithms fall
+back to Insertion Sort.
+
+If we cannot make fewer comparisons, perhaps we can make each of them faster? `strcmp()` compares
+characters one at a time. It cannot read ahead as it can be illegal to touch memory past the first
+null byte. But _we_ know that it's safe to read a few extra bytes past the end of `d_name` for every
+entry except the last in the buffer. And since we own the buffer, we can overallocate it so that
+reading past the end of the last entry is also safe.
+
+Combining these ideas with the fact that file names on Linux are at most 255 bytes long, we can
+invoke `getdents64()` like this:
+
+```c++
+int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize - 256);
+```
+
+And then compare entries like this:
+
+```c++
+[](const char* a, const char* b) { return memcmp(a, b, 255) < 0; }
+```
+
+This version doesn't give any speedup compared to the previous but it opens an avenue for another
+optimization. The pointers we pass to `memcmp()` aren't aligned. To be more specific, their
+numerical values are `N * 8 + 3` for some `N`. When given such a pointer, `memcmp()` will check the
+first 5 bytes one by one, and only then switch to comparing 8 bytes at a time. If we can handle the
+first 5 bytes ourselves, we can pass aligned memory to `memcmp()` and take full advantage of its
+vectorized loop.
+
+Here's the implementation:
+
+```c++
+uint64_t Read64(const void* p) {                                                          // +
+  uint64_t x;                                                                             // +
+  memcpy(&x, p, sizeof(x));                                                               // +
+  return x;                                                                               // +
+}                                                                                         // +
+
+void ByteSwap64(void* p) {                                                                // +
+  uint64_t x = __builtin_bswap64(Read64(p));                                              // +
+  memcpy(p, &x, sizeof(x));                                                               // +
+}                                                                                         // +
+
+void ListDir(int parent_fd, Arena& arena, vector<char*>& entries) {
+  entries.clear();
+  int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC);
+  if (dir_fd < 0) return;
+  arena.Clear();
+  while (true) {
+    char* buf = arena.Alloc();
+    int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize - 256);                // +
+    if (n <= 0) {
+      if (n) entries.clear();
+      break;
+    }
+    for (int pos = 0; pos < n;) {
+      auto* ent = reinterpret_cast<dirent64_t*>(buf + pos);
+      if (!Dots(ent->d_name)) {
+        ByteSwap64(ent->d_name);                                                          // +
+        entries.push_back(ent->d_name);
+      }
+      pos += ent->d_reclen;
+    }
+  }
+  sort(entries.begin(), entries.end(), [](const char* a, const char* b) {
+    uint64_t x = Read64(a);                                                               // +
+    uint64_t y = Read64(b);                                                               // +
+    return x < y || (x == y && a != b && memcmp(a + 5, b + 5, 256) < 0);                  // +
+  });
+  for (char* p : entries) ByteSwap64(p);                                                  // +
+  close(dir_fd);
+}
+```
+
+This is for Little Endian architecture. Big Endian doesn't need `ByteSwap64()`, so it'll be a bit
+faster.

+## Conclusion
+
+Through a series of incremental improvements we've sped up directory listing by 43.3% compared to a
+naive implementation (v1) and 27.2% compared to a reasonable implementation that a seasoned C/C++
+practitioner might write (v2).
+
+However, these numbers are based on an artificial benchmark while the real judge is always the real
+code. Our goal was to speed up gitstatusd. Benchmark was just a tool. Thankfully, the different
+versions of `ListDir()` have the same comparative performance within gitstatusd as in the benchmark.
+In truth, the directory chosen for the benchmark wasn't arbitrary. It was picked by sampling
+gitstatusd when it runs on [chromium](https://github.com/chromium/chromium) git repository.
+
+The final version of `ListDir()` spends 97% of its CPU time in the kernel. If we assume that it
+makes the minimum possible number of system calls and these calls are optimal (true to the best
+of my knowledge), it puts the upper bound on possible future performance improvements at just 3%.
+There is almost nothing left in `ListDir()` to optimize.

+If positional arguments are specified, call this on success:

+  CMD [ARG]... DAEMON VERSION INSTALLED
+
+DAEMON is path to gitstatusd. VERSION is a glob pattern for the
+version this daemon should support; it's supposed to be passed as
+-G to gitstatusd. INSTALLED is 1 if gitstatusd has just been
+downloaded and 0 otherwise.
+
+Options:
+
+  -s KERNEL  use this instead of lowercase `uname -s`
+  -m ARCH    use this instead of lowercase `uname -m`
+  -d DIR     use this instead of `dirname "$0"`
+  -p CMD     eval this every second while downloading gitstatusd
+  -e ERRFD   write error messages to this file descriptor
+  -f         download gitstatusd even if there is one locally
+  -n         do not download gitstatusd (fail instead)

+# This script does not have a stable API.
+#
+# Usage: mbuild [-b git-ref] [kernel-arch]...
+#
+# Builds a bunch of gitstatusd-* binaries. Without arguments builds binaries
+# for all platforms. git-ref defaults to master.
+#
+# Before using this script you need to set up build servers and list them
+# in ~/.ssh/config. There should be a Host entry for every value of `assets`
+# association defined below. VMs and cloud instances work as well as physical
+# machines, including localhost. As long as the machine has been set up as
+# described below and you can SSH to it without password, it should work.
+#
+#                    ===[ Build Server Setup ]===
+#
+#                              Linux
+#
+# - Install docker.
+#   $ apt install docker.io     # adjust appropriately if there is no `apt`
+#   $ usermod -aG docker $USER  # not needed if going to build as root
+# - Install git.
+#   $ apt install git           # adjust appropriately if there is no `apt`
+#
+#                              macOS
+#
+# - Install compiler tools:
+#   $ xcode-select --install
+# - Install homebrew: https://brew.sh/.
+#   $ bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
+#
+#                             FreeBSD
+#
+# - Install git.
+#   $ pkg install git
+#
+#                             Windows
+#
+# - Disable Windows Defender (optional).
+#   ps> Set-MpPreference -DisableRealtimeMonitoring $true
+# - Install 64-bit and 32-bit msys2: https://www.msys2.org/wiki/MSYS2-installation/.
+#   - Open each of them after installation, type `pacman -Syu --noconfirm` and close the window.
+#   - Then run in powershell while having no msys2 or cygwin windows open:
+#     ps> C:\msys32\autorebase.bat
+#     ps> C:\msys64\autorebase.bat
+# - Install 64-bit and 32-bit cygwin: https://cygwin.com/install.html.
+#   - Choose to install 32-bit to c:/cygwin32 instead of the default c:/cygwin.
+#   - Select these packages: binutils, cmake, gcc-core, gcc-g++, git, make, perl, wget.
+#
+# IMPORTANT: Install msys2 and cygwin one at a time.
+#
+# IMPORTANT: msys2 builder can reboot the build machine.
+#
+# Option 1: OpenSSH for Windows
+#
+# - Install OpenSSH: https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse.
+#   ps> Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
+#   ps> Start-Service sshd
+#   ps> Set-Service -Name sshd -StartupType 'Automatic'
+# - Enable publickey authentication: https://stackoverflow.com/a/50502015/1095235.
+#   ps> cd $env:USERPROFILE
+#   ps> mkdir .ssh
+#   ps> notepad.exe .ssh/authorized_keys
+#     - Paste your public key, save, close.
+#   ps> icacls .ssh/authorized_keys /inheritance:r
+#   ps> notepad.exe C:\ProgramData\ssh\sshd_config
+#     - Comment out these two lines, save, close:
+#       # Match Group administrators
+#       #   AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys
+#   ps> Restart-Service sshd
+#
+# Option 2: OpenSSH from WSL
+#
+# - Install WSL.
+# - Install Ubuntu.
+# - Install sshd.
+#   $ apt install openssh-server
+#   $ dpkg-reconfigure openssh-server
+#   $ cat >/etc/ssh/sshd_config <<\END

+## Usage: gitstatus_query [OPTION]... NAME
+#
+#   -d STR    Directory to query. Defaults to the current directory. Has no effect if GIT_DIR
+#             is set.
+#   -c STR    Callback function to call once the results are available. Called only after
+#             gitstatus_query returns 0 with VCS_STATUS_RESULT=tout.
+#   -t FLOAT  Timeout in seconds. Negative value means infinity. Will block for at most this long.
+#             If no results are available by then: if -c isn't specified, will return 1; otherwise
+#             will set VCS_STATUS_RESULT=tout and return 0.
+#   -p        Don't compute anything that requires reading Git index. If this option is used,
+#             the following parameters will be 0: VCS_STATUS_INDEX_SIZE,
+#             VCS_STATUS_{NUM,HAS}_{STAGED,UNSTAGED,UNTRACKED,CONFLICTED}.
+#
+# On success sets VCS_STATUS_RESULT to one of the following values:

+#   tout         Timed out waiting for data; will call the user-specified callback later.
+#   norepo-sync  The directory isn't a git repo.
+#   ok-sync      The directory is a git repo.
+#
+# When the callback is called, VCS_STATUS_RESULT is set to one of the following values:
+#
+#   norepo-async  The directory isn't a git repo.
+#   ok-async      The directory is a git repo.
