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