This is a variant of the Flex fast lexical scanner. Flex was written in the early 1990s by Verne Paxson. This version has been modified by Thomas Dickey, so that it conforms to ANSI C. It includes other improvements, but remains compatible with Paxson's 2.5.4 release (as well as POSIX lex). See the NEWS file for details. WWW: https://invisible-island.net/reflex/
