- """Pynche -- The PYthon Natural Color and Hue Editor.
-
- Contact: Barry Warsaw
- Email: bwarsaw@python.org
- 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 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] [-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
-
- --help
- -h
- print this message
-
- initialcolor
- initial color, as a color name or #RRGGBB format
