How about we put the trace name in front and don't have the PID as the

Yep, maybe it's best to really do something about the order...

What about doing date prefixing followed by the trace name and if
necessary followed by a seq nr?

Something like

20101109-152301-auto
20101109-152301-auto_1 (in case of collision?)

We might also consider putting the actual application name (the first
stripped token of argv[0] in there?

Hmmm, there is a lot of information in these path for now lol.

usttrace should also be consider for a change I think. It is unusable to my opinion having this date format of 24 numbers... and only numbers that in a long run become human "not readable".

So how about this :

${HOME}/.usttraces/$hostname-$app_name/20101109-152301-$tracename-$PID

Regrouping all traces from the same apps and host.. ?

Include the name of the trace to the output directory created by
