$ cd /home/chris/dev/
$ hg init newwiki
$ cd newwiki
$ mkdir plugins tpl
$ cd plugins
$ for r in ../../dokuwiki/plugins/* do ; hg pull -f $r ${r##*/} ; done
$ cd ../tpl
$ hg pull -f ../../dokuwiki/tpl/roundbox roundbox
$ cd ../..
$ mv dokuwiki dokuwiki.orig # Just to still have it around
$ mv newwiki dokuwiki
