= _procage_: when was a Linux process started

While _ps_ will give you a summarized version of when a process
started, it shows less and less precision the older the process is.
It's sometimes useful to know precisely when this happened, especially
for old processes; hence, _[[procage.py </~cks/programs/linux/procage.py>]]_.

Usage: procage.py [-a] PID [PID ...]

If given a _-a_ argument, _procage.py_ reports the process's age in
seconds instead of its start time.

This is Linux specific, since it uses Linux's _/proc_ information.
