[PEAK] WorkingSet and sys.path

[Leonardo Giordani]

Hi all,

I'm working on the following code (based on some code found on the 
documentation):

import pkg_resources as pr
ws = pr.WorkingSet()
d,e = ws.find_plugins(pr.Environment())
map(ws.add, d)
epmap = pr.get_entry_map(d[0])
getver = pr.load_entry_point(d[0], 'common', 'getVersionAndDependencies')

I expected ws.add to add each entry in d to my sys.path, but the latter 
remains unchanged, so executing load_entry_point fails because the module 
cannot be imported.

Probably I misunderstood how to use WorkingSet: anyone can help me?
My goal is to develop a plugin system for a Python application.

Thank you in advance

Leonardo Giordani
