True. Meanwhile I studied the provided examples ;-)

Almost. ;-)

I'm writing a remote frontend for pbuilder. It handles exporting source 
packages from svn-buildpackage repositories and/or applies 
distribution-specific patches to ease backporting. It also handles versions 
mangling for backports (with recently became much easier, thanks to ~).

Modified or unmodified source packages are then uploaded to a remote
build machine and pbuilder is invoked on that machine. Afterwards build
results are downloaded.

I wrote this, because I have a single machine in our lab that runs
pbuilder and has a number of basetgzs on it -- for all dists (sarge, etch,
breezy and dapper) and platforms (i386 and amd64) we have in our lab. 
I found no tool that could recompile a downloaded source
package for a certain distribution, so I tried to write my own.

Meanwhile it works pretty well. But quite often a simple recompile for backports
fails (mostly because of simple dependency issues). I'm currently adding a
--{pre|post}build-login option to my script that allows for interactive
logins on the buildmachine to handle such issues. The script generates
the necessary hook script by itself.

Cheers,

Michael
