VirtualBox appliance
To facilitate trying out MirrorBrain, there is a VirtualBox Appliance which contains an openSUSE 11.1 system with an up-to-date MirrorBrain install.
The image is about 1.3G in size and can be downloaded from http://mirrorbrain.org/eval/openSUSE_11.1/ or rsync'ed from rsync://mirrorbrain.org/mirrorbrain-eval/ .
There is a README file containing further notes useful to set up the image.
SVN Repository
All code lives in a Subversion repository which can be checked out with the following command:
svn checkout http://svn.mirrorbrain.org/svn/mirrorbrain/trunk/ mirrorbrain
The tree can also be browsed via ViewVC.

Notes for packagers
