    (description
     "@code{re2c} generates minimalistic hard-coded state machine (as opposed
to full-featured table-based lexers).  A flexible API allows generated code
to be wired into virtually any environment.  Instead of exposing a traditional
@code{yylex()} style API, re2c exposes its internals.  Be sure to take a look
at the examples, as they cover a lot of real-world cases and shed some light on
dark corners of the re2c API.")
