Heroku buildpack: Python

========================

This is a [Heroku buildpack](http://devcenter.heroku.com/articles/buildpacks) for Python apps.

It uses [virtualenv](http://www.virtualenv.org/) and [pip](http://www.pip-installer.org/).

[![Build Status](https://secure.travis-ci.org/heroku/heroku-buildpack-python.png?branch=master)](http://travis-ci.org/heroku/heroku-buildpack-python)

Usage

-----

Example usage:

    $ ls

    Procfile  requirements.txt  web.py

    $ heroku create --stack cedar --buildpack git://github.com/heroku/heroku-buildpack-python.git

    $ git push heroku master

    ...

    -----> Heroku receiving push

    -----> Fetching custom build pack... done

    -----> Python app detected

    -----> Preparing virtualenv version 1.6.4

           New python executable in ./bin/python

           Installing setuptools............done.

           Installing pip...............done.

    -----> Installing dependencies using pip version 1.0.2

           Successfully installed Flask Werkzeug Jinja2

           Cleaning up...

You can also add it to upcoming builds of an existing application:

    $ heroku config:add BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-python.git

The buildpack will detect your app as Python if it has the file `requirements.txt` in the root. It will detect your app as Python/Django if there is an additional `settings.py` in a project subdirectory.

It will use virtualenv and pip to install your dependencies, vendoring a copy of the Python runtime into your slug.  The `bin/`, `include/` and `lib/` directories will be cached between builds to allow for faster pip install time.

Hacking

-------

To use this buildpack, fork it on Github.  Push up changes to your fork, then create a test app with `--buildpack ` and push to it.

To change the vendored virtualenv, unpack the desired version to the `src/` folder, and update the virtualenv() function in `bin/compile` to prepend the virtualenv module directory to the path. The virtualenv release vendors its own versions of pip and setuptools.
