+ (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.")
