"""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
