# LexGen.py - implemented 2002 by Neil Hodgson neilh@scintilla.org
# Released to the public domain.
# Regenerate the Scintilla and SciTE source files that list
# all the lexers and all the properties files.
# Should be run whenever a new lexer is added or removed.
# Requires Python 2.4 or later
# Most files are regenerated in place with templates stored in comments.
# The VS .NET project file is generated into a different file as the
# VS .NET environment will not retain comments when modifying the file.
# The format of generation comments is documented in FileGenerator.py.
