Required tools: diff3, kdiff3, kompare

ksvn just gets called like the standard svn tool:
ksvn <command> (see svn help)

ksvn normally just calls svn with the supplied arguments.
The following subcommands are treated specially though:

• up | update | merge
  we add the --diff3-cmd parameter pointing to ourselves.
  This will call kdiff3 for every merge with a conflict that can't be handled by diff3.

• diff
  we just call svn diff and pipe the output to kompare.

• adiff
  alt diff: same as diff but with additional parameters for diff, which makes reviewing a patch a bit simpler (-dbu5).
