+Description: Ragel is State Machine Compiler
+
+Ragel compiles executable finite state machines from regular languages. Ragel
+targets C, C++, Objective-C, D, Java 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.
+
+This is version prebuilt on Ubuntu Lucid and thus it should be compatible with
+all major Linux distributions.

...that have ia32-libs installed

I am too lazy to rephrase it fully, suggest to leave this:
This is a 32bit version prebuilt on Ubuntu Lucid.
