+ * scan.h - the jam yacc scanner
+ *
+ * External functions:
+ *
+ *	yyerror( char *s ) - print a parsing error message
+ *	yyfparse( char *s ) - scan include file s
+ *	yylex() - parse the next token, returning its type
+ *	yymode() - adjust lexicon of scanner
+ *	yyparse() - declaration for yacc parser
+ *	yyanyerrors() - indicate if any parsing errors occured
+ *
+ * The yymode() function is for the parser to adjust the lexicon of the
+ * scanner.  Aside from normal keyword scanning, there is a mode to
+ * handle action strings (look only for the closing }) and a mode to 
+ * ignore most keywords when looking for a punctuation keyword.  This 
+ * allows non-punctuation keywords to be used in lists without quoting.
