+// Previous releases of this lexer included support for marking token starts with
+// a style byte indicator. This was used by the wxGhostscript IDE/debugger.
+// Style byte indicators were removed in version 3.4.3.
+// Anyone wanting to restore this functionality for wxGhostscript using 'modern'
+// indicators can examine the earlier source in the Mercurial repository.
