+# 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 2.1 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.

+# and the digit and next character are not part of the definition
+# Backslash is used as an escape within the definition line.
+# The part between \( and \) is repeated for each item in the list.
