[Python-ideas] Add appdirs module to stdlib

[M.-A. Lemburg]

I just commented on the ticket that references this discussion:

http://bugs.python.org/issue7175

In essence, Python already has an installation scheme which is
defined in sysconfig.py (see the top of the file) and has had
this ever since distutils got added to the stdlib.

It just lacks explicit entries for "config" and "cache" files,
so adding those would be more in line with coming up with
yet another standard, e.g. for posix_user:

    'posix_user': {
        'stdlib': '{userbase}/lib/python{py_version_short}',
        'platstdlib': '{userbase}/lib/python{py_version_short}',
        'purelib': '{userbase}/lib/python{py_version_short}/site-packages',
        'platlib': '{userbase}/lib/python{py_version_short}/site-packages',
        'include': '{userbase}/include/python{py_version_short}',
        'scripts': '{userbase}/bin',
        'config': '{userbase}/etc',
        'cache': '{userbase}/var',
        'data': '{userbase}',
        },

({userbase} is set by looking at PYTHONUSERBASE and defaults to
~/.local/)
