 A complete output of the "pristine-tar checkout" of all files is stored on <https://gist.github.com/836720> .
 
 For now, I'll download the `.tar.gz` from <http://packages.debian.org/unstable/source/ikiwiki>, or maybe install `ikiwiki_3.20110124_all.deb`. Would you recommend using that `.deb` file on Ubuntu 10.04.2 LTS, or is it Debian-specific? -- [[sunny256]] 2011-02-21 08:42+0100
