-# 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 files are copied to a string apart from sections between a
-# ++Autogenerated comment and a --Autogenerated comment which is
-# generated by the CopyWithInsertion function. After the whole
-# string is instantiated, it is compared with the target file and
-# if different the file is rewritten.
-# Does not regenerate the Visual C++ 6 project files but does the VS .NET
-# project file.
