     26  * esclex.h -- public definitions for esclex module
     27  *
     28  * this module provides lexical analysis (i.e. tokenizing the
     29  * input files) and the lex-level error routines expected by
     30  * yacc like yyerror().  yylex() and yyerror() are called only
     31  * by yacc-generated code.  the lex_X() routines are called
     32  * only by main().
     33  *
     34  * the tokstr struct is the communication mechanism between the lexer
     35  * and the parser.
