  40     (description
  41      "Ragel compiles executable finite state machines from regular languages.
  42 Ragel targets C, C++, Obj-C, C#, D, Java, Go and Ruby.  Ragel state machines
  43 can not only recognize byte sequences as regular expression machines do, but
  44 can also execute code at arbitrary points in the recognition of a regular
  45 language.  Code embedding is done using inline operators that do not disrupt
  46 the regular language syntax.")
