|
|
This file is normally created by easy_install / distutils in
|
|
site-packages and overrides python's default site.py. It adds
|
|
all parts of PYTHONPATH as site directories, which means pth
|
|
files are processed in them. We remove the normally created
|
|
site.py's and package it separately instead as it would cause
|
|
collisions.
|
|
|
|
For each module we have a pth file listing the module and all
|
|
its dependencies and we include python-site into the
|
|
PYTHONPATH of wrapped python programs so they can find their
|
|
dependencies.
