This is a Heroku buildpack for Python apps, powered by pip.
It is a conversion of a Heroku buildpack that includes pre-built binaries of numpy and scipy. Further information can be made on this StackOverflow answer.
Example usage:
$ ls
app.py Procfile README.md requirements.txt
$ heroku create --stack cedar --buildpack git://github.com/kmp1/heroku-buildpack-python.git
$ git push heroku master

Cleaning up...
You can also add it to upcoming builds of an existing application:
$ heroku config:add BUILDPACK_URL=git://github.com/kmp1/heroku-buildpack-python.git
The buildpack will detect your app as Python if it has the file requirements.txt in the root.
It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.
You can also provide arbitrary releases Python with a runtime.txt file.
$ cat runtime.txt
python-3.3.0
Runtime options include:
- python-2.7.4
- python-3.3.1
- pypy-1.9 (experimental)
