- * Title: Miniature lexer for C++ parser.
- *
- * File Name: CxxLexer.l
- *
- * Author: E.D.Willink
- *
- * This is a complete lexer for C++, intended for use with CxxParser.y.
- * All actions are done by macros, so that there is some chance that customisation
- * can be performed within the bounds of the CxxLexing.hxx and CxxLexing.cxx
- * include files.
