   IDE. Linux,Windows,Mac. PyGTK

   I'll try that.  I have come across tagmanager (C) code written for
the Anjuta (http://anjuta.org) project.  I should give it a try too.

   I will put it in brief.  The class browser can't support all
standard and third party python packages, since most of them is
available as shared objects.  So mine is focused only on the current
project, i.e. user created (or application) python files.  So the
browser should be able to fetch the tags (class, functions, methods)
from source code along with the line number information.  That's all
about.  Any further possiblities in this regard is also expected.
