DESC="\
flex (fast lexical analyzer generator)                                 \n\
                                                                       \n\
flex is a tool for generating programs that perform pattern matching   \n\
on text.  flex is a rewrite of the AT&T Unix lex tool (the two         \n\
implementations do not share any code, though), with some extensions   \n\
(and incompatibilities)."
