To people using yacc & lex and trying to read from a file, not stdin,
you should note that in the code generated by lex for reading a character,
a call is made to getc(yyin).
	yyin is simply a variable statically initialized to be stdin, but
you can *easily* re-assign it via a call to fopen(), as in
	yyin = fopen(argv[1])
	or some such.
	Look at the code generated by these tools!  It's easy to change it!
