 // external interface provided to flex C++ lexer objects, and yyFlexLexer,
 // which defines a particular lexer class.
 //
 // If you want to create multiple lexer classes, you use the -P flag
 // to rename each yyFlexLexer to some other xxFlexLexer.  You then
 // include <FlexLexer.h> in your other sources once per lexer class:
 //
 //  #undef yyFlexLexer
 //  #define yyFlexLexer xxFlexLexer
 //  #include <FlexLexer.h>
 //
 //  #undef yyFlexLexer
 //  #define yyFlexLexer zzFlexLexer
 //  #include <FlexLexer.h>
