# LexGen.py - implemented 2002 by Neil Hodgson neilh@scintilla.org
# Released to the public domain.

# Regenerate the Scintilla source files that list all the lexers.
# Should be run whenever a new lexer is added or removed.
# Requires Python 2.5 or later
# Files are regenerated in place with templates stored in comments.
# The format of generation comments is documented in FileGenerator.py.
