This module adds a "magic" __main__.py that turns a zip file of dependencies
into something that can be appended to Python script.
Example:
pip install --target ./deps/ -r myscript.reqs magicmain PYTHONPATH=./deps/ ./myscript.py # Check that it works (cd deps/ ; zip -r ../deps.zip .) cat zips.zip >> myscript.py ./myscript.py # Should work!
