Description-en: Documentation for an old flex (a fast lexical analyzer generator)
This package contains the HTML documentation for the old 2.5.4a version
of flex, which is no longer being developed upstream. You should
normally chose flex-doc, unless you have legacy lexer files that do
not work with a modern flex, and need to use the old flex. The
upstream source code can be found at the FTP site:
