Here are some code snipits from our project.  I hope they help.  I did
not code it, Someone else patched it to use multiple links.  You can
find the project homepage along with a few screenshots here:
http://porthole.sourceforge.net/

The source file of the snipits, summary.py here:

        # can highlight URL links & change mouse pointer
