# Ok, so I'm using ImageMagick. Why reinvent the wheel?

# Modes
# Basic functionality for this at the moment. You've got input in TML
# (Transferable Markup Language; like HTML, only different) and output
# in HTML (hmmm...) WML (WAP Markup Language. One of my inspirations for this)
# and plain ASCII text with things like *italic* and !bold!. Don't know about those
# last formatting things, may take 'em off or put them in a seperate mode.
#
# 0 - PNG (default)
# 1 - JPEG
# 2 - GIF (Warning - may still be legal issues)
# 3 - BMP
# 4 - WBMP (default for WAP browsers)
