**
** The buckwheat filter
** 	by Benjamin Elijah Griffin 	29 March 1995
**
** A lex utility written as a favor for a friend. (He provided the
** rules, I showed him how to make a lex filter out of them.)
**
** compile like this:
**		lex buck.l
**		cc -o buck lex.yy.c -ll
**		rm lex.yy.c
**
** use like this:
**		buck < infile > outfile
**	or
**		cat infile | <whatever> | buck | <whatever> > outfile
**
