## Example Zope product that monkey patches the IssueTrackerProduct

# Zope
from zLOG import LOG, INFO

# our big brother
from Products.IssueTrackerProduct import IssueTracker
# NB: If we write IssueTracker.IssueTracker
#        we mean <IssueTracker.py>.<class IssueTracker>


#-----------------------------------------------------------------------------
# Now, let's test if we should go ahead with this at all
#

# assume that we won't be able to do it
do_patch = False 

# Let's only go ahead with this if the issuetracker
# version is above 0.6.4

#-----------------------------------------------------------------------------
# We write our own functions that are (to us) vastly superior to those of the
# default IssueTrackerProduct

#-----------------------------------------------------------------------------
# Finally, do the actual monkey patch
#
if do_patch:
    # add a new attribute to the class which happens to be 
    # an overwriting. You can add more functions to the class
    # too if you need to.
