if you look at that page, you can see those nice boxes with nice colors.. dokuwiki currently has <code> and <file>, however, it does not have a nice way of giving a filename, or a brief description, and as you can see here:
http://wiki.kaspersandberg.com/doku.php?id=projects:emerge-wrapper
that can be a problem, since this doesent look as nice as what mediawiki does :)
also notice the second green code box, where its 1 code fox, with 2 sections, one for showing the command, and second for what to input into the command.. this is REALLY nice behavior, i still think a normal box like the one dokuwiki has now should exist, but one should have the ability to use a box like the ones on mediawiki, on gentoo-wiki.org
