It's a mess with the location of pwb documentation. We have several places but where is the right one?
we have the old place meta since 2005: http://meta.wikimedia.org/wiki/Pywikipediabot?uselang=de but also mediawiki since 2005 which is corresponding to mw software itself: http://www.mediawiki.org/w/index.php?title=Pywikipediabot&dir=prev&l... Also wikibooks gives us http://en.wikibooks.org/wiki/Pywikibot Guess when it was created. All 3 versions are quite similar. And you can find a lot of other manuals and guids all over the world, most of them are deprecated in parts.
