The website for tidier is up and running again for those that want to 
use it.

(We have had serious trouble with the air conditioning system in the lab 
and several disks have been hit or mounted read only since last Friday.)

FYI: Tidier is using the same infrastructure as erl_tidy, namely the 
erl_prettypr module, and its output is untidied in similar respects, I 
am afraid. Not much can be done about it, at least until the parser is 
adapted to also maintain comments and white spaces.
