CLAWK is an AWK implementation embedded into Common Lisp, by Michael Parker. Michael Weber patched it to make it compile again; his version is here: http://www.foldr.org/~michaelw/lisp/clawk/ This version was created by Zach Beane to fix an SBCL compile-time warning about a bogus format string. https://github.com/sharplispers/clawk 2011-10-31
