Explanations

In plain words, this license means that I don't want the fame, but I will not take the blame either. You may reuse jgz as you wish for any purpose, provided that you understand that I am not to be considered responsible for anything in any circumstance. The license text above is copied in the jgz source files, and should be kept in the source files as long as their content can be traced back to me: this is for my own protection. Apart from that, there is no need to cite me anywhere (neither in the acknowledgements, advertising or accompanying documentation), although it could be viewed as a courteous gesture to drop me a mail in case you reuse jgz and find it great (or not -- I gladly accept bug reports as well).

The whole license issue is quite fishy. "Public Domain" is a tempting notion, but it is difficult to achieve worldwide without any fear of future legal entanglement, especially with some juridictions which prohibit an author from abandoning the so-called "moral rights" (I currently live in France, and French law enforces such moral rights). The only sure way to put some code in the Public Domain seems to be a combination of publishing, then dying, and then waiting for almost a century and fervently hoping that copyright laws are not modified in the mean time. I therefore use the "MIT License" because it does what I want without requiring my demise, and since that license has been around for some time, it seems quite resilient to attacks from enraged lawyers.
