The Plex module provides lexical analysers with similar capabilities
to GNU Flex. The following classes and functions are exported;
see the attached docstrings for more information.

   Scanner          For scanning a character stream under the
                    direction of a Lexicon.

   Lexicon          For constructing a lexical definition
                    to be used by a Scanner.

   Str, Any, AnyBut, AnyChar, Seq, Alt, Opt, Rep, Rep1,
   Bol, Eol, Eof, Empty

                    Regular expression constructors, for building pattern
                    definitions for a Lexicon.

   State            For defining scanner states when creating a
                    Lexicon.

   TEXT, IGNORE, Begin

                    Actions for associating with patterns when
        creating a Lexicon.
