This is a repo designed to be used as a submodule for other packages that test and build python packages on OSX.
There are bash functions to call for installing Python from Python.org downloads (with given version), Macports and Homebrew. Each of these can then be used to create a virtualenv in which to install and test packages.
If you only need the Python.org installers (which are a reasonable default choice), then prefer the multibuild project, which gets more development attention.
There are also simple bash functions for installing libraries using classic configure / make / install, or via cmake, and some utilities for working with waf
See matplotlib-wheels for an example of using terryfy for a complicated build.
