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.
