Quite right. My use of the term "proper credit" was silly as each license
defines what proper credit is. Source code copyright is retained by the
original author. However, one can fork GPL code, change it's name and most
users wouldn't necessarily realise. To some people (such as the Xfree86
guys) that might not constitute "proper credit".

Indeed, although a fair number of the other licenses (such as the BSD ones)
would involve even greater "relaxation" by the author.

No, I was referring to GPL, but I was wrong :-)
