Recover deleted FFS files

[Frank Wille <frank%phoenix.owl.de@localhost>]

Hi,

I found surpisingly few about the topic of undeleting files. Let's assume I
have a FFSv2 WAPBL filesystem and made the big mistake to delete a whole
directory with important data (simple "rm -rf", no -P).
What options do I have for recovery?
