Clarify what would be released to Pypi and what are the dependencies

[andy-maier]

It is not clear to me what would be released to Pypi:

• One Pypi package containing both subdirectories?
• Two Pypi packages, each containing one subdirectory?
• Only some module-level functionality from the code, but not the entire apache modules?

Second, what are the Python dependencies and OS-level dependencies of the Pypi packages?

To be released:
Not clear for me either. I would probably be simpler to install everything, in a first stage: There is not a lot of code anyway. But first, it might be better that I fix "apxs" issue, and do more tests.

Dependencies:
werkzeug
mako, possibly optional.
selinux, Linux only, and possibly optional.
markupsafe

OS-level Dependencies:

• Windows 10
• WSL (that is, Linux)
  I have to do more tests also, but the changes done when porting to Python 3 are very local, so the dependencies should not have changed. Will investigate more.
