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