[Zope] CMF Portal Catalog issue(Please Reply urgently)

[Ashish Gautam]

Hello,
         I have a problem with ZCatalog in my CMF site.
         Lately i checked that the objects indexed by Portal_Catalog  has
increased by a very large extent. When i checked i found that the Portal
Catalog has started indexing 
the python sripts and Page Template files which form a part of the code for
my site. I dont know why these entries have started coming up.
Any ideas

Regards,
Yaser
