+## `pyenv local`
+
+Sets a local application-specific Python version by writing the version
+name to a `.python-version` file in the current directory. This version
+overrides the global version, and can be overridden itself by setting
+the `PYENV_VERSION` environment variable or with the `pyenv shell`
+command.
+
+    $ pyenv local 2.7.6
+
+When run without a version number, `pyenv local` reports the currently
+configured local version. You can also unset the local version:
+
+    $ pyenv local --unset
+
+Previous versions of pyenv stored local version specifications in a
+file named `.pyenv-version`. For backwards compatibility, pyenv will
+read a local version specified in an `.pyenv-version` file, but a
+`.python-version` file in the same directory will take precedence.
+
+
+### `pyenv local` (advanced)
+
+You can specify multiple versions as local Python at once.
+
+Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
+
+    $ pyenv local 2.7.6 3.3.3
+    $ pyenv versions
+      system
+    * 2.7.6 (set by /Users/yyuu/path/to/project/.python-version)
+    * 3.3.3 (set by /Users/yyuu/path/to/project/.python-version)
+    $ python --version
+    Python 2.7.6
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+or, if you prefer 3.3.3 over 2.7.6,
+
+    $ pyenv local 3.3.3 2.7.6
+    $ pyenv versions
+      system
+    * 2.7.6 (set by /Users/yyuu/path/to/project/.python-version)
+    * 3.3.3 (set by /Users/yyuu/path/to/project/.python-version)
+      venv27
+    $ python --version
+    Python 3.3.3
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+
+## `pyenv global`
+
+Sets the global version of Python to be used in all shells by writing
+the version name to the `~/.pyenv/version` file. This version can be
+overridden by an application-specific `.python-version` file, or by
+setting the `PYENV_VERSION` environment variable.
+
+    $ pyenv global 2.7.6
+
+The special version name `system` tells pyenv to use the system Python
+(detected by searching your `$PATH`).
+
+When run without a version number, `pyenv global` reports the
+currently configured global version.
+
+
+### `pyenv global` (advanced)
+
+You can specify multiple versions as global Python at once.
+
+Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
+
+    $ pyenv global 2.7.6 3.3.3
+    $ pyenv versions
+      system
+    * 2.7.6 (set by /Users/yyuu/.pyenv/version)
+    * 3.3.3 (set by /Users/yyuu/.pyenv/version)
+    $ python --version
+    Python 2.7.6
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+or, if you prefer 3.3.3 over 2.7.6,
+
+    $ pyenv global 3.3.3 2.7.6
+    $ pyenv versions
+      system
+    * 2.7.6 (set by /Users/yyuu/.pyenv/version)
+    * 3.3.3 (set by /Users/yyuu/.pyenv/version)
+      venv27
+    $ python --version
+    Python 3.3.3
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+
+## `pyenv shell`
+
+Sets a shell-specific Python version by setting the `PYENV_VERSION`
+environment variable in your shell. This version overrides
+application-specific versions and the global version.
+
+    $ pyenv shell pypy-2.2.1
+
+When run without a version number, `pyenv shell` reports the current
+value of `PYENV_VERSION`. You can also unset the shell version:
+
+    $ pyenv shell --unset
+
+Note that you'll need pyenv's shell integration enabled (step 3 of
+the installation instructions) in order to use this command. If you
+prefer not to use shell integration, you may simply set the
+`PYENV_VERSION` variable yourself:
+
+    $ export PYENV_VERSION=pypy-2.2.1
+
+
+### `pyenv shell` (advanced)
+
+You can specify multiple versions via `PYENV_VERSION` at once.
+
+Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
+
+    $ pyenv shell 2.7.6 3.3.3
+    $ pyenv versions
+      system
+    * 2.7.6 (set by PYENV_VERSION environment variable)
+    * 3.3.3 (set by PYENV_VERSION environment variable)
+    $ python --version
+    Python 2.7.6
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+or, if you prefer 3.3.3 over 2.7.6,
+
+    $ pyenv shell 3.3.3 2.7.6
+    $ pyenv versions
+      system
+    * 2.7.6 (set by PYENV_VERSION environment variable)
+    * 3.3.3 (set by PYENV_VERSION environment variable)
+      venv27
+    $ python --version
+    Python 3.3.3
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+

+
+[![Build Status](https://travis-ci.org/yyuu/pyenv.svg)](https://travis-ci.org/yyuu/pyenv)
+
+pyenv lets you easily switch between multiple versions of Python. It's
+simple, unobtrusive, and follows the UNIX tradition of single-purpose
+tools that do one thing well.
+
+This project was forked from [rbenv](https://github.com/sstephenson/rbenv) and
+[ruby-build](https://github.com/sstephenson/ruby-build), and modified for Python.

+### pyenv _does..._
+
+* Let you **change the global Python version** on a per-user basis.
+* Provide support for **per-project Python versions**.
+* Allow you to **override the Python version** with an environment
+  variable.
+* Search commands from **multiple versions of Python at a time**.
+  This may be helpful to test across Python versions with [tox](http://pypi.python.org/pypi/tox).
+

+
+* **Depend on Python itself.** pyenv was made from pure shell scripts.
+    There is no bootstrap problem of Python.
+* **Need to be loaded into your shell.** Instead, pyenv's shim
+    approach works by adding a directory to your `$PATH`.
+* **Manage virtualenv.** Of course, you can create [virtualenv](http://pypi.python.org/pypi/virtualenv)
+    yourself, or [pyenv-virtualenv](https://github.com/yyuu/pyenv-virtualenv)

-rbenv is a version manager tool for the Ruby programming language on Unix-like systems. It is useful for switching between multiple Ruby versions on the same machine and for ensuring that each project you are working on always runs on the correct Ruby version.
 
 ## How It Works
 
-After rbenv injects itself into your PATH at installation time, any invocation of `ruby`, `gem`, `bundler`, or other Ruby-related executable will first activate rbenv. Then, rbenv scans the current project directory for a file named `.ruby-version`. If found, that file determines the version of Ruby that should be used within that directory. Finally, rbenv looks up that Ruby version among those installed under `~/.rbenv/versions/`.
+At a high level, pyenv intercepts Python commands using shim
+executables injected into your `PATH`, determines which Python version
+has been specified by your application, and passes your commands along
+to the correct Python installation.
 
-You can choose the Ruby version for your project with, for example:
-```sh
-cd myproject
-# choose Ruby version 3.1.2:
-rbenv local 3.1.2
-```
 
-Doing so will create or update the `.ruby-version` file in the current directory with the version that you've chosen. A different project of yours that is another directory might be using a different version of Ruby altogether—rbenv will seamlessly transition from one Ruby version to another when you switch projects.
+### Understanding PATH
 
-Finally, almost every aspect of rbenv's mechanism is [customizable via plugins][plugins] written in bash.
+When you run a command like `python` or `pip`, your operating system
+searches through a list of directories to find an executable file with
+that name. This list of directories lives in an environment variable
+called `PATH`, with each directory in the list separated by a colon:
+
+    /usr/local/bin:/usr/bin:/bin
+
+Directories in `PATH` are searched from left to right, so a matching
+executable in a directory at the beginning of the list takes
+precedence over another one at the end. In this example, the
+`/usr/local/bin` directory will be searched first, then `/usr/bin`,
+then `/bin`.
+
+
+### Understanding Shims
+
+pyenv works by inserting a directory of _shims_ at the front of your
+`PATH`:
+
+    ~/.pyenv/shims:/usr/local/bin:/usr/bin:/bin
+
+Through a process called _rehashing_, pyenv maintains shims in that
+directory to match every Python command across every installed version
+of Python—`python`, `pip`, and so on.
+
+Shims are lightweight executables that simply pass your command along
+to pyenv. So with pyenv installed, when you run, say, `pip`, your
+operating system will do the following:
+
+* Search your `PATH` for an executable file named `pip`
+* Find the pyenv shim named `pip` at the beginning of your `PATH`
+* Run the shim named `pip`, which in turn passes the command along to
+  pyenv
+
+
+### Choosing the Python Version
+
+When you execute a shim, pyenv determines which Python version to use by
+reading it from the following sources, in this order:
+
+1. The `PYENV_VERSION` environment variable (if specified). You can use
+   the [`pyenv shell`](#pyenv-shell) command to set this environment
+   variable in your current shell session.
+
+2. The application-specific `.python-version` file in the current
+   directory (if present). You can modify the current directory's
+   `.python-version` file with the [`pyenv local`](#pyenv-local)
+   command.
+
+3. The first `.python-version` file found (if any) by searching each parent
+   directory, until reaching the root of your filesystem.
+
+4. The global `~/.pyenv/version` file. You can modify this file using
+   the [`pyenv global`](#pyenv-global) command. If the global version
+   file is not present, pyenv assumes you want to use the "system"
+   Python. (In other words, whatever version would run if pyenv weren't in your
+   `PATH`.)
+
+**NOTE:** You can activate multiple versions at the same time, including mulitple
+versions of Python2 or Python3 simultaneously. This allows for parallel usage of
+Python2 and Python3, and is required with tools like `tox`. For example, to set
+your path to first use your `system` Python and Python3 (set to 2.7.9 and 3.4.2
+in this example), but also have Python 3.3.6, 3.2, and 2.5 available on your
+`PATH`, one would first `pyenv install` the missing versions, then set `pyenv
+global system 3.3.6 3.2 2.5`. At this point, one should be able to find the full
+executable path to each of these using `pyenv which`, e.g. `pyenv which python2.5`
+(should display `$PYENV_ROOT/versions/2.5/bin/python2.5`), or `pyenv which
+python3.4` (should display path to system Python3).
+
+### Locating the Python Installation
+
+Once pyenv has determined which version of Python your application has
+specified, it passes the command along to the corresponding Python
+installation.
+
+Each Python version is installed into its own directory under
+`~/.pyenv/versions`.
+
+For example, you might have these versions installed:
+
+* `~/.pyenv/versions/2.7.8/`
+* `~/.pyenv/versions/3.4.2/`
+* `~/.pyenv/versions/pypy-2.4.0/`
+
+As far as pyenv is concerned, version names are simply the directories in
+`~/.pyenv/versions`.

-The simplicity of rbenv has its benefits, but also some downsides. See the [comparison of version managers][alternatives] for more details and some alternatives.
 
 ## Installation
 
-On systems with Homebrew package manager, the “Using Package Managers” method is recommended. On other systems, “Basic Git Checkout” might be the easiest way of ensuring that you are always installing the latest version of rbenv.
+If you're on Mac OS X, consider [installing with Homebrew](#homebrew-on-mac-os-x).
 
-### Using Package Managers
 
-1. Install rbenv using one of the following approaches.
+### The automatic installer
 
-   #### Homebrew
-   
-   On macOS or Linux, we recommend installing rbenv with [Homebrew](https://brew.sh).
-   
-   ```sh
-   brew install rbenv
-   ```
-   
-   #### Debian, Ubuntu, and their derivatives
-       
-   > [!CAUTION]   
-   > The version of rbenv that is packaged and maintained in official
-   Debian and Ubuntu repositories is _out of date_. To install the latest
-   version, it is recommended to [install rbenv using git](#basic-git-checkout).
-   
-   ```sh
-   sudo apt install rbenv
-   ```
-   
-   #### Arch Linux and its derivatives
-   
-   Archlinux has an [AUR Package](https://aur.archlinux.org/packages/rbenv/) for
-   rbenv and you can install it from the AUR using the instructions from this
-   [wiki page](https://wiki.archlinux.org/index.php/Arch_User_Repository#Installing_and_upgrading_packages).
+Visit my other project:
+https://github.com/yyuu/pyenv-installer
 
-   #### Fedora
 
-   Fedora has an [official package](https://packages.fedoraproject.org/pkgs/rbenv/rbenv/) which you can install:
+### Basic GitHub Checkout
 
-   ```sh
-   sudo dnf install rbenv
-   ```
+This will get you going with the latest version of pyenv and make it
+easy to fork and contribute any changes back upstream.
 
-2. Set up your shell to load rbenv.
+1. **Check out pyenv where you want it installed.**
+   A good place to choose is `$HOME/.pyenv` (but you can install it somewhere else).
 
-    ```sh
-    rbenv init
-    ```
+        $ git clone https://github.com/yyuu/pyenv.git ~/.pyenv
 
-3. Close your Terminal window and open a new one so your changes take effect.
 
-That's it! You are now ready to [install some Ruby versions](#installing-ruby-versions).
+2. **Define environment variable `PYENV_ROOT`** to point to the path where
+   pyenv repo is cloned and add `$PYENV_ROOT/bin` to your `$PATH` for access
+   to the `pyenv` command-line utility.
 
-### Basic Git Checkout
+        $ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bash_profile
+        $ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bash_profile
 
-> [!NOTE]   
-> For a more automated install, you can use [rbenv-installer](https://github.com/rbenv/rbenv-installer#rbenv-installer). If you do not want to execute scripts downloaded from a web URL or simply prefer a manual approach, follow the steps below.
+    **Zsh note**: Modify your `~/.zshenv` file instead of `~/.bash_profile`.
+    **Ubuntu note**: Modify your `~/.bashrc` file instead of `~/.bash_profile`.
 
-This will get you going with the latest version of rbenv without needing a system-wide install.
+3. **Add `pyenv init` to your shell** to enable shims and autocompletion.
+   Please make sure `eval "$(pyenv init -)"` is placed toward the end of shell
+   configuration file since it manipulates `PATH` during the initialization.
 
-1. Clone rbenv into `~/.rbenv`.
+        $ echo 'eval "$(pyenv init -)"' >> ~/.bash_profile
 
-    ```sh
-    git clone https://github.com/rbenv/rbenv.git ~/.rbenv
-    ```
+    **Zsh note**: Modify your `~/.zshenv` file instead of `~/.bash_profile`.
+    **Ubuntu note**: Modify your `~/.bashrc` file instead of `~/.bash_profile`.
+    
+    **General warning**: There are some systems, where the `BASH_ENV` variable is configured
+    to point to `.bashrc`. On such systems you should almost certainly put the abovementioned line
+    `eval "$(pyenv init -)` into `.bash_profile`, and **not** into `.bashrc`. Otherwise you
+    may observe strange behaviour, such as `pyenv` getting into an infinite loop.
+    See [#264](https://github.com/yyuu/pyenv/issues/264) for details.
 
-2. Set up your shell to load rbenv.
+4. **Restart your shell so the path changes take effect.**
+   You can now begin using pyenv.
 
-    ```sh
-    ~/.rbenv/bin/rbenv init
-    ```
+        $ exec $SHELL
 
-   If you are curious, see here to [understand what `init` does](#how-rbenv-hooks-into-your-shell).
+5. **Install Python versions into `$PYENV_ROOT/versions`.**
+   For example, to install Python 2.7.8, download and unpack the source, then run:
 
-3. Restart your shell so that these changes take effect. (Opening a new terminal tab will usually do it.)
+        $ pyenv install 2.7.8
 
-#### Shell completions
+   **NOTE:** If you need to pass configure option to build, please use
+   ```CONFIGURE_OPTS``` environment variable.
 
-When _manually_ installing rbenv, it might be useful to note how completion scripts for various shells work. Completion scripts help with typing rbenv commands by expanding partially entered rbenv command names and option flags; typically this is invoked by pressing <kbd>Tab</kbd> key in an interactive shell.
+   **NOTE:** If you are having trouble installing a python version,
+   please visit the wiki page about
+   [Common Build Problems](https://github.com/yyuu/pyenv/wiki/Common-build-problems)
 
-- The **bash** completion script for rbenv ships with the project and gets [loaded by the `rbenv init` mechanism](#how-rbenv-hooks-into-your-shell).
+6. **Rebuild the shim binaries.**
+   You should do this any time you install a new Python binary.
+   (Examples: installing a new Python version, or installing a package that provides a binary.)
 
-- The **zsh** completion script ships with the project, but needs to be added to FPATH in zsh before it can be discovered by the shell. One way to do this would be to edit `~/.zshrc`:
+        $ pyenv rehash
 
-  ```sh
-  # assuming that rbenv was installed to `~/.rbenv`
-  FPATH=~/.rbenv/completions:"$FPATH"
+   This can be automated for pip using
+   [pyenv-pip-rehash](https://github.com/yyuu/pyenv-pip-rehash), which invokes
+   `pyenv rehash` after (un)installing packages using pip.
 
-  autoload -U compinit
-  compinit
-  ```
 
-- The **fish** completion script for rbenv ships with the fish shell itself and is not maintained by the rbenv project.
+#### Upgrading
 
-### Installing Ruby versions
+If you've installed pyenv using the instructions above, you can
+upgrade your installation at any time using git.
 
-The `rbenv install` command does not ship with rbenv out-of-the-box, but is provided by the [ruby-build][] plugin.
+To upgrade to the latest development version of pyenv, use `git pull`:
 
-Before attempting to install Ruby, **check that [your build environment](https://github.com/rbenv/ruby-build/wiki#suggested-build-environment) has the necessary tools and libraries**. Then:
+    $ cd ~/.pyenv
+    $ git pull
 
-```sh
-# list latest stable versions:
-rbenv install -l
+To upgrade to a specific release of pyenv, check out the corresponding tag:
 
-# list all local versions:
-rbenv install -L
+    $ cd ~/.pyenv
+    $ git fetch
+    $ git tag
+    v0.1.0
+    $ git checkout v0.1.0
 
-# install a Ruby version:
-rbenv install 3.1.2
-```
 
-For troubleshooting `BUILD FAILED` scenarios, check the [ruby-build Discussions section](https://github.com/rbenv/ruby-build/discussions/categories/build-failures).
+### Homebrew on Mac OS X
 
-> [!NOTE]  
-> If the `rbenv install` command wasn't found, you can install ruby-build as a plugin:
-> ```sh
-> git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
-> ```
+You can also install pyenv using the [Homebrew](http://brew.sh)
+package manager for Mac OS X.
 
-Set a Ruby version to finish installation and start using Ruby:
-```sh
-rbenv global 3.1.2   # set the default Ruby version for this machine
-# or:
-rbenv local 3.1.2    # set the Ruby version for this directory
-```
+    $ brew update
+    $ brew install pyenv
 
-Alternatively to the `rbenv install` command, you can download and compile Ruby manually as a subdirectory of `~/.rbenv/versions`. An entry in that directory can also be a symlink to a Ruby version installed elsewhere on the filesystem.
 
-#### Installing Ruby gems
+To upgrade pyenv in the future, just use `upgrade` instead of `install`.
 
-Select a Ruby version for your project using `rbenv local 3.1.2`, for example. Then, proceed to install gems as you normally would:
+After installation, you'll still need to add `eval "$(pyenv init -)"` to your
+profile (as stated in the caveats). You'll only ever have to do this
+once.
 
-```sh
-gem install bundler
-```
 
-> [!NOTE]  
-> You _should not use sudo_ to install gems. Typically, the Ruby versions will be installed under your home directory and thus writeable by your user. If you get the “you don't have write permissions” error when installing gems, it's likely that your "system" Ruby version is still a global default. Change that with `rbenv global <version>` and try again.
+### Neckbeard Configuration
 
-Check the location where gems are being installed with `gem env`:
+Skip this section unless you must know what every line in your shell
+profile is doing.
 
-```sh
-gem env home
-# => ~/.rbenv/versions/<version>/lib/ruby/gems/...
-```
+`pyenv init` is the only command that crosses the line of loading
+extra commands into your shell. Coming from rvm, some of you might be
+opposed to this idea. Here's what `pyenv init` actually does:
 
-#### Uninstalling Ruby versions
+1. **Sets up your shims path.** This is the only requirement for pyenv to
+   function properly. You can do this by hand by prepending
+   `~/.pyenv/shims` to your `$PATH`.
 
-As time goes on, Ruby versions you install will accumulate in your
-`~/.rbenv/versions` directory.
+2. **Installs autocompletion.** This is entirely optional but pretty
+   useful. Sourcing `~/.pyenv/completions/pyenv.bash` will set that
+   up. There is also a `~/.pyenv/completions/pyenv.zsh` for Zsh
+   users.
 
-To remove old Ruby versions, simply `rm -rf` the directory of the
-version you want to remove. You can find the directory of a particular
-Ruby version with the `rbenv prefix` command, e.g. `rbenv prefix
-2.7.0`.
+3. **Rehashes shims.** From time to time you'll need to rebuild your
+   shim files. Doing this on init makes sure everything is up to
+   date. You can always run `pyenv rehash` manually.
+
+4. **Installs the sh dispatcher.** This bit is also optional, but allows
+   pyenv and plugins to change variables in your current shell, making
+   commands like `pyenv shell` possible. The sh dispatcher doesn't do
+   anything crazy like override `cd` or hack your shell prompt, but if
+   for some reason you need `pyenv` to be a real script rather than a
+   shell function, you can safely skip it.
+
+To see exactly what happens under the hood for yourself, run `pyenv init -`.
+
+
+### Uninstalling Python Versions
+
+As time goes on, you will accumulate Python versions in your
+`~/.pyenv/versions` directory.
+
+To remove old Python versions, `pyenv uninstall` command to automate
+the removal process.
+
+Alternatively, simply `rm -rf` the directory of the version you want
+to remove. You can find the directory of a particular Python version
+with the `pyenv prefix` command, e.g. `pyenv prefix 2.6.8`.
+
+
+----
 
-The [ruby-build][] plugin provides an `rbenv uninstall` command to
-automate the removal process.
 
 ## Command Reference
 
-The main rbenv commands you need to know are:
-
-### rbenv versions
-
-Lists all Ruby versions known to rbenv, and shows an asterisk next to
-the currently active version.
-
-    $ rbenv versions
-      1.8.7-p352
-      1.9.2-p290
-    * 1.9.3-p327 (set by /Users/sam/.rbenv/version)
-      jruby-1.7.1
-      rbx-1.2.4
-      ree-1.8.7-2011.03
-
-### rbenv version
-
-Displays the currently active Ruby version, along with information on
-how it was set.
-
-    $ rbenv version
-    1.9.3-p327 (set by /Users/sam/.rbenv/version)
-
-### rbenv local
-
-Sets a local application-specific Ruby version by writing the version
-name to a `.ruby-version` file in the current directory. This version
-overrides the global version, and can be overridden itself by setting
-the `RBENV_VERSION` environment variable or with the `rbenv shell`
-command.
-
-    rbenv local 3.1.2
-
-When run without a version number, `rbenv local` reports the currently
-configured local version. You can also unset the local version:
-
-    rbenv local --unset
-
-### rbenv global
-
-Sets the global version of Ruby to be used in all shells by writing
-the version name to the `~/.rbenv/version` file. This version can be
-overridden by an application-specific `.ruby-version` file, or by
-setting the `RBENV_VERSION` environment variable.
-
-    rbenv global 3.1.2
-
-The special version name `system` tells rbenv to use the system Ruby
-(detected by searching your `$PATH`).
-
-When run without a version number, `rbenv global` reports the
-currently configured global version.
-
-### rbenv shell
-
-Sets a shell-specific Ruby version by setting the `RBENV_VERSION`
-environment variable in your shell. This version overrides
-application-specific versions and the global version.
-
-    rbenv shell jruby-1.7.1
-
-When run without a version number, `rbenv shell` reports the current
-value of `RBENV_VERSION`. You can also unset the shell version:
-
-    rbenv shell --unset
-
-Note that you'll need rbenv's shell integration enabled (step 3 of
-the installation instructions) in order to use this command. If you
-prefer not to use shell integration, you may simply set the
-`RBENV_VERSION` variable yourself:
-
-    export RBENV_VERSION=jruby-1.7.1
-
-### rbenv rehash
-
-Installs shims for all Ruby executables known to rbenv (`~/.rbenv/versions/*/bin/*`). Typically you do not need to run this command, as it will run automatically after installing gems.
-
-    rbenv rehash
-
-### rbenv which
-
-Displays the full path to the executable that rbenv will invoke when
-you run the given command.
-
-    $ rbenv which irb
-    /Users/sam/.rbenv/versions/1.9.3-p327/bin/irb
-
-### rbenv whence
-
-Lists all Ruby versions that contain the specified executable name.
-
-    $ rbenv whence rackup
-    1.9.3-p327
-    jruby-1.7.1
-    ree-1.8.7-2011.03
-
-## Environment variables
-
-You can affect how rbenv operates with the following settings:
-
-name | default | description
------|---------|------------
-`RBENV_VERSION` | | Specifies the Ruby version to be used.<br>Also see [`rbenv shell`](#rbenv-shell)
-`RBENV_ROOT` | `~/.rbenv` | Defines the directory under which Ruby versions and shims reside.<br>Also see `rbenv root`
-`RBENV_DEBUG` | | Outputs debug information.<br>Also as: `rbenv --debug <subcommand>`
-`RBENV_HOOK_PATH` | [_see wiki_][hooks] | Colon-separated list of paths searched for rbenv hooks.
-`RBENV_DIR` | `$PWD` | Directory to start searching for `.ruby-version` files.
-
-### How rbenv hooks into your shell
-
-`rbenv init` is a helper command to hook rbenv into a shell. This helper is part of the recommended installation instructions, but optional, as an experienced user can set up the following tasks manually. The `rbenv init` command has two modes of operation:
-
-1. `rbenv init`: made for humans, this command edits your shell initialization files on disk to add rbenv to shell startup. (Prior to rbenv 1.3.0, this mode only printed user instructions to the terminal, but did nothing else.)
-
-2. `rbenv init -`: made for machines, this command outputs a shell script suitable to be eval'd by the user's shell.
-
-When `rbenv init` is invoked from a bash shell, for example, it will add the following to the user's `~/.bashrc` or `~/.bash_profile`:
-
-```sh
-# Added by `rbenv init` on <DATE>
-eval "$(rbenv init - --no-rehash bash)"
-```
-
-You may add this line to your shell initialization files manually if you want to avoid running `rbenv init` as part of the setup process. Here is what the eval'd script does:
-
-0. Adds `rbenv` executable to PATH if necessary.
-
-1. Prepends `~/.rbenv/shims` directory to PATH. This is basically the only requirement for rbenv to function properly.
-
-2. Installs bash shell completion for rbenv commands.
-
-3. Regenerates rbenv shims. If this step slows down your shell startup, you can invoke `rbenv init -` with the `--no-rehash` flag.
-
-4. Installs the "sh" dispatcher. This bit is also optional, but allows rbenv and plugins to change variables in your current shell, making commands like `rbenv shell` possible.
+See [COMMANDS.md](COMMANDS.md).
 
 
-### Uninstalling rbenv
+----
 
-The simplicity of rbenv makes it easy to temporarily disable it, or
-uninstall from the system.
-
-1. To **disable** rbenv managing your Ruby versions, simply comment or remove the `rbenv init` line from your shell startup configuration. This will remove rbenv shims directory from PATH, and future invocations like `ruby` will execute the system Ruby version, bypassing rbenv completely.
-
-   While disabled, `rbenv` will still be accessible on the command line, but your Ruby apps won't be affected by version switching.
-
-2. To completely **uninstall** rbenv, perform step (1) and then remove the rbenv root directory. This will **delete all Ruby versions** that were installed under `` `rbenv root`/versions/ ``:
-
-       rm -rf "$(rbenv root)"
-
-   If you've installed rbenv using a package manager, as a final step
-   perform the rbenv package removal:
-   - Homebrew: `brew uninstall rbenv`
-   - Debian, Ubuntu, and their derivatives: `sudo apt purge rbenv`
-   - Archlinux and its derivatives: `sudo pacman -R rbenv`
 
 ## Development
 
-Tests are executed using [Bats](https://github.com/bats-core/bats-core):
+The pyenv source code is [hosted on GitHub](https://github.com/yyuu/pyenv).
+It's clean, modular, and easy to understand--even if you're not a shell hacker.

+# python-build
+
+python-build is a [pyenv](https://github.com/yyuu/pyenv) plugin
+that provides a `pyenv install` command to compile and install
+different versions of Python on UNIX-like systems.
+
+You can also use python-build without pyenv in environments where you
+need precise control over Python version installation.
+
+
+## Installation
+
+### Installing as an pyenv plugin (recommended)
+
+You need nothing to do since python-build is bundled with pyenv by
+default.
+
+### Installing as a standalone program (advanced)
+
+Installing python-build as a standalone program will give you access to
+the `python-build` command for precise control over Python version
+installation. If you have pyenv installed, you will also be able to
+use the `pyenv install` command.
+
+    git clone git://github.com/yyuu/pyenv.git
+    cd pyenv/plugins/python-build
+    ./install.sh
+
+This will install python-build into `/usr/local`. If you do not have
+write permission to `/usr/local`, you will need to run `sudo
+./install.sh` instead. You can install to a different prefix by
+setting the `PREFIX` environment variable.
+
+To update python-build after it has been installed, run `git pull` in
+your cloned copy of the repository, then re-run the install script.
+
+
+## Usage
+
+### Using `pyenv install` with pyenv
+
+To install a Python version for use with pyenv, run `pyenv install` with
+the exact name of the version you want to install. For example,
+
+    pyenv install 2.7.4
+
+Python versions will be installed into a directory of the same name
+under `~/.pyenv/versions`.
+
+To see a list of all available Python versions, run `pyenv install --list`.
+You may also tab-complete available Python
+versions if your pyenv installation is properly configured.
+
+### Using `python-build` standalone
+
+If you have installed python-build as a standalone program, you can use
+the `python-build` command to compile and install Python versions into
+specific locations.
+
+Run the `python-build` command with the exact name of the version you
+want to install and the full path where you want to install it. For
+example,
+
+    python-build 2.7.4 ~/local/python-2.7.4
+
+To see a list of all available Python versions, run `python-build
+--definitions`.
+
+Pass the `-v` or `--verbose` flag to `python-build` as the first
+argument to see what's happening under the hood.
+
+### Custom definitions
+
+Both `pyenv install` and `python-build` accept a path to a custom
+definition file in place of a version name. Custom definitions let you
+develop and install versions of Python that are not yet supported by
+python-build.
+
+See the [python-build built-in
+definitions](https://github.com/yyuu/pyenv/tree/master/plugins/python-build/share/python-build)
+as a starting point for custom definition files.
+
+### Special environment variables
+
+You can set certain environment variables to control the build
+process.
+
+* `TMPDIR` sets the location where python-build stores temporary files.
+* `PYTHON_BUILD_BUILD_PATH` sets the location in which sources are
+  downloaded and built. By default, this is a subdirectory of
+  `TMPDIR`.
+* `PYTHON_BUILD_CACHE_PATH`, if set, specifies a directory to use for
+  caching downloaded package files.
+* `PYTHON_BUILD_MIRROR_URL` overrides the default mirror URL root to one
+  of your choosing.
+* `PYTHON_BUILD_SKIP_MIRROR`, if set, forces python-build to download
+  packages from their original source URLs instead of using a mirror.
+* `CC` sets the path to the C compiler.
+* `CONFIGURE_OPTS` lets you pass additional options to `./configure`.
+* `MAKE` lets you override the command to use for `make`. Useful for
+  specifying GNU make (`gmake`) on some systems.
+* `MAKE_OPTS` (or `MAKEOPTS`) lets you pass additional options to
+  `make`.
+* `PYTHON_CONFIGURE_OPTS` and `PYTHON_MAKE_OPTS` allow you to specify
+  configure and make options for buildling CPython. These variables will
+  be passed to Python only, not any dependent packages (e.g. libyaml).
+
+### Building as `--enable-shared`
+
+You can build CPython with `--enable-shared` to install a version with
+shared object.
+
+If `--enabled-shared` was found in `PYTHON_CONFIGURE_OPTS` or `CONFIGURE_OPTS`,
+`python-build` will automatically set `RPATH` to the pyenv's prefix directory.
+This means you don't have to set `LD_LIBRARY_PATH` or `DYLD_LIBRARY_PATH` for
+the version(s) installed with `--enable-shared`.
+
+```sh
+$ env PYTHON_CONFIGURE_OPTS="--enable-shared` pyenv install 2.7.9
+```
+
+### Checksum verification
+
+If you have the `shasum`, `openssl`, or `sha256sum` tool installed,
+python-build will automatically verify the SHA2 checksum of each
+downloaded package before installing it.
+
+Checksums are optional and specified as anchors on the package URL in
+each definition. (All bundled definitions include checksums.)
+
+### Package download mirrors
+
+python-build will first attempt to download package files from a mirror
+hosted on Amazon CloudFront. If a package is not available on the
+mirror, if the mirror is down, or if the download is corrupt,
+python-build will fall back to the official URL specified in the
+defintion file.
+
+You can point python-build to another mirror by specifying the
+`PYTHON_BUILD_MIRROR_URL` environment variable--useful if you'd like to
+run your own local mirror, for example. Package mirror URLs are
+constructed by joining this variable with the SHA2 checksum of the
+package file.
+
+If you don't have an SHA2 program installed, python-build will skip the
+download mirror and use official URLs instead. You can force
+python-build to bypass the mirror by setting the
+`PYTHON_BUILD_SKIP_MIRROR` environment variable.
+
+The official python-build download mirror is provided by [Git Hub Pages](http://yyuu.github.io/pythons/).
+
+### Package download caching
+
+You can instruct python-build to keep a local cache of downloaded
+package files by setting the `PYTHON_BUILD_CACHE_PATH` environment
+variable. When set, package files will be kept in this directory after
+the first successful download and reused by subsequent invocations of
+`python-build` and `pyenv install`.
+
+The `pyenv install` command defaults this path to `~/.pyenv/cache`, so
+in most cases you can enable download caching simply by creating that
+directory.
+
+### Keeping the build directory after installation
+
+Both `python-build` and `pyenv install` accept the `-k` or `--keep`
+flag, which tells python-build to keep the downloaded source after
+installation. This can be useful if you need to use `gdb` and
+`memprof` with Python.
+
+Source code will be kept in a parallel directory tree
+`~/.pyenv/sources` when using `--keep` with the `pyenv install`
+command. You should specify the location of the source code with the
+`PYTHON_BUILD_BUILD_PATH` environment variable when using `--keep` with
+`python-build`.
+
+
+## Getting Help
+
+Please see the [python-build
+wiki](https://github.com/yyuu/pyenv/wiki) for solutions to
+common problems.
+
+If you can't find an answer on the wiki, open an issue on the [issue
+tracker](https://github.com/yyuu/pyenv/issues). Be sure to
+include the full build log for build failures.
