[Python-Dev] Usefulness of site-python?

Hello,

I've just discovered there is a little-known feature in site.py: if a
$PREFIX/lib/site-python exists (e.g. /usr/lib/site-python), it is added
to sys.path in addition to the versioned site-packages. But only under
Unix ("if os.sep == '/'").

Has anyone seen that feature in the real world? Debian doesn't use
site-python, but its own /usr/share/pyshared.

For the record, it was added in b53347c8260e with the following commit
message:

user:        Guido van Rossum <guido at python.org>
date:        Wed Sep 03 21:41:30 1997 +0000
files:       Lib/site.py
description:
Give in to Mike Meyer -- add *both* lib/python1.5/packages and
lib/site-python to the path (if they exist).  This is a reasonable
compromise.


Regards

Antoine.
