For those of us who knew about the incident but not the nitty-gritty details -- "What is Ragel?"<p>> Ragel compiles executable finite state machines from regular languages. Ragel targets C, C++ and ASM. 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.<p>> What kind of task is Ragel good for?<p>> Writing robust protocol implementations.
