.pth files

[Sylvain Thenault]

Hi there !

I've some questions regarding pth files (which btw are undocumented in the
python reference, is this intentional ?)

I thought that I could use a .pth file to be able to import zope products
from both INSTANCE_HOME/Products and ZOPE_HOME/lib/python/Products from
outside zope:


syt at musca:~$ cat cvs_work/Products.pth 
/home/syt/local/Zope-2.8.1-b1/Products
/home/syt/local/Zope-2.8.1-b1/lib/python/Products
syt at musca:~$ 
syt at musca:~$ python
Python 2.3.5 (#2, Jun 19 2005, 13:28:00) 
[GCC 3.3.6 (Debian 1:3.3.6-6)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> print sys.path
['', '/home/syt/cvs_work', '/home/syt/cvs_work/prive/soft', 
 '/home/syt/local/lib/python2.3/site-packages',
 '/home/syt/local/lib/python', '/usr/lib/python23.zip',
 '/usr/lib/python2.3', '/usr/lib/python2.3/plat-linux2',
 '/usr/lib/python2.3/lib-tk', '/usr/lib/python2.3/lib-dynload',
 '/usr/local/lib/python2.3/site-packages',
 '/usr/lib/python2.3/site-packages',
 '/usr/lib/python2.3/site-packages/Numeric',
 '/usr/lib/python2.3/site-packages/PIL',
 '/usr/lib/python2.3/site-packages/gtk-2.0',
 '/usr/lib/python2.3/site-packages/vtk_python', '/usr/lib/site-python']

But as you can see, 
1. the Products.pth file isn't considered at all, while for example
   PIL.pht in the site-packages is correctly detected
2. I'm not even sure that I can put several paths in a .pth file

Is there a restriction on .pth location ? Is it possible to have multiple
path in a pth file ?
