"""Pynche -- The PYthon Natural Color and Hue Editor.
|
||
|
||
Contact: %(AUTHNAME)s
|

Email: %(AUTHEMAIL)s
|
||
Version: %(__version__)s
|
||
|
||
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 2.2 with Tkinter.
|
||
|
||
Usage: %(PROGRAM)s [-d file] [-i file] [-X] [-v] [-h] [initialcolor]
|
||
|
||
Where:
|
||
--database file
|
||
-d file
|
||
Alternate location of a color database file
|
||
|
||
--initfile file
|
||
-i file
|
||
Alternate location of the initialization file. This file contains a
|
||
persistent database of the current Pynche options and color. This
|
||
means that Pynche restores its option settings and current color when
|
||
it restarts, using this file (unless the -X option is used). The
|
||
default is ~/.pynche
|
||
|
||
--ignore
|
||
-X
|
||
Ignore the initialization file when starting up. Pynche will still
|
||
write the current option settings to this file when it quits.
|
||
|
||
--version
|
||
-v
|
||
print the version number and exit
|
||
|
||
--help
|
||
-h
|
||
print this message
|
||
|
||
initialcolor
|
||
initial color, as a color name or #RRGGBB format
