"""Pynche: The PYthon Natural Color and Hue Editor.
Pynche is based largely on a similar color editor I wrote years ago for the
Sunview window system. That editor was called ICE: the Interactive Color
Editor. I'd always wanted to port the editor to X but didn't feel like
hacking X and C code to do it. Fast forward many years, to where Python +
Tkinter provides such a nice programming environment, with enough power, that
I finally buckled down and implemented it. I changed the name because these
days, too many other systems have the acronym `ICE'.
This program currently requires Python 1.5 with Tkinter. It has only been
tested on Solaris 2.6. Feedback is greatly appreciated. Send email to
bwarsaw@python.org
Usage: %(PROGRAM)s [-d file] [-h] [initialcolor]
Where:
--database file
-d file
Alternate location of a color database file
--help
-h
print this message
initialcolor
initial color, as a color name or #RRGGBB format
