define help

Supported targets: prepare, develop, sdist, clean, test, and pypi.

The 'prepare' target installs Epitome's build requirements into the current virtualenv.

The 'develop' target creates an editable install of Epitome and its runtime requirements in the
current virtualenv. The install is called 'editable' because changes to the source code
immediately affect the virtualenv.

The 'clean' target undoes the effect of 'develop'.

The 'test' target runs Epitome's unit tests. Set the 'tests' variable to run a particular test, e.g.

        make test tests=epitome/test/models_test.py:test

The 'pypi' target publishes the current commit of Epitome to PyPI after enforcing that the working
copy and the index are clean, and tagging it as an unstable .dev build.
