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