<?
# Calendar.php - creates a calendar gif with current day highlighted
# resultant gif has transparent background to black, can easily be changed
# and uses the datecode as it's name ex:(20000204.gif)
# 
# and is free to everyone, but don't sell it without asking first
# and you don't even have to give me credit if you use it!
# feel free to drop me a line and let me know.
