 *  that are just as good or better, but I like these tools 
 *  because I personally wrote them, so I know their quirks.
 *  (i.e. I know where the bodies are buried).  I want to 
 *  make sure that I can re-use these utilities for whatever
 *  code I may want to write in the future be it
 *  proprietary or open-source, so I've put them under
 *  a very, very permissive license.
 *
 *  If you find this code useful, use it.  If not, don't.
