There is one problem with wikibooks. Namely: All text is available under the terms of the GNU Free Documentation License.
After some surfing on the net I found this: GPL incompatible in both directions The GNU FDL is incompatible in both directions with the GPL: that is GNU FDL material cannot be put into GPL code and GPL code cannot be put into a GNU FDL manual. Because of this, code samples are often dual-licensed so that they may appear in documentation and can be incorporated into a free software program. At the June 22nd and 23rd international GPLv3 conference in Barcelona, Moglen hinted that a future version of the GPL could be made suitable for documentation: "By expressing LGPL as just an additional permission on top of GPL we simplify our licensing landscape drastically. It's like for physics getting rid of a force, right? We just unified electro-weak, ok? The grand unified field theory still escapes us until the document licences too are just additional permissions on top of GPL. I don't know how we'll ever get there, that's gravity, it's really hard." http://en.wikipedia.org/wiki/GNU_Free_Documentation_License Other links: http://www.debian.org/News/2006/20060316 http://trends.newsforge.com/article.pl?sid=06/03/13/1615216&from=rss http://community.linux.com/community/05/08/03/194222.shtml?tid=11 So it seems that GFDL is not suitable for a cookbook where the tips may end up in GPL or similar licensesed scripts... Any thoughts? Preben
