docbook-xsl is necessary to build the package without network access.

other files are being removed by dh_clean debian/clean file!

01-adjust_config_basedir.diff
02-gcc-4.4-fixes.diff
04-revert_cross_compile.diff

it turns out that zsh and bash have a too different behavior.

the combination of the following svn revisions is causing trouble when
trying to compile boxbackup on debian systems:

 - 2485
 - 2484
 - 2483

reverting 2483 alone doesn't help, I had to revert all of them.
