  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.
