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