+>> Thanks for your responses, smcv. I'll use that method and install the newest version when I'm more familiar with the way ikiwiki works. For now I'm using version 3.20100122 installed with apt-get. Works great so far, but I'm looking forward to the new install. -- [[sunny256]] 2011-02-22 19:30+0100

 The operation fails on these files with a "Checksum validation failed" error from `xdelta`(1). The `pristine-tar`(1) version is 1.00, installed with `apt-get` on Ubuntu 10.04.2 LTS. Is this version too old, or are there some errors on this branch?
