	It's quite easy.  There are some things missing from my example here that
you will need to create, alot of dtml and an __init__.py file which sets up some
stuff and contains the ImageFile references to any icons you plan to use.  Notice
I just droped this stuff like iceing onto your Calendar cake.  It looks daunting
now but after you see it a few times lots of the fluf because invisible to you.
