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