✏️ Editing: plastik_theme.py

"""This demonstrates good part of the syntax accepted by theme_create.

This is a translation of plastik.tcl to python.
You will need the images used by the plastik theme to test this. The
images (and other tile themes) can be retrived by doing:

$ cvs -z3 -d:pserver:anonymous@tktable.cvs.sourceforge.net:/cvsroot/tktable \
  co tile-themes

To test this module you should do, for example:

import Tkinter
import plastik_theme

root = Tkinter.Tk()
plastik_theme.install(plastik_image_dir)
...

Where plastik_image_dir contains the path to the images directory used by
the plastik theme, something like: tile-themes/plastik/plastik
