* Write a good HOWTO (any help welcome). It should not be as verbose as
  tla-buildpackage docs, similar to the one from cvs-buildpackage but
  written with SGML (debiandoc) and outline special features of
  svn-buildpackage scripts
* make layout option to be treated in a single place and abstract it
  away for all the commands that take it into account
  - done for svn-inject
* check thouroughly if s-u needs to use svnMkdirP; on first glance it
  should not; maybe is safer to call svnMkdirP preemptively on all
  detected of configured $$c{".*Url"} urls in order to fix breakage
  introduced in l2 packages injected with old versions of svn-bp
