PyEdit Editor Code

#!/usr/bin/env python

# ------------------------------------------------------------------------
# This is open source editor. Written on python. The motivation for 
# this project was to create a modern multi-platform editor. 
# Simple, powerful, configurable, extendable. 
#
# Pyedit has:
#
#    o  macro recording/play, 
#    o  search/replace, 
#    o  functional navigation,
#    o  comment/string spell check, 
#    o  auto backup, 
#    o  persistent undo/redo, 
#    o  auto complete, auto correct, 
#    o  ... and a lot more. 
#
# It is fast, it is extendable, as python lends itself to easy tinkering. 
# The editor has a table driven key mapping. One can easily edit the key 
# map in keyhand.py, and the key actions in acthand.py The default key map 
# resembles gedit / wed / etp / brief

# ASCII only, fixed font only. For now ... Requires pygtk.
