firstly thanks for your wonderful work :)
Just one thing I'd like to add:
The language string for the basedir and the baseurl definitely needs a precise explanation.
"Base directory" to "Base directory (e.g. /dokuwiki/)"
"Base URL" to "Base URL (e.g. http://www.yourserver.com:port)"
I think its not just me who enters /www/htdocs/wiki as base dir and example.com/wiki/ as base url.
This costs some time in finding the problem and can be avoided easily.
(RTFM, you're right. Anyway DokuWiki is breaking the common rules here ;-) )
