Try to figure out what's eating your cpu cycles.  Break down the
problem into smaller pieces.  Concentrate on the problem part.
Once you know *where* it is going wrong, the *why* usually is
found quite easely.

It's probably something to do with the interaction between perl
and grep.  I'm no perl guru so I shut up right now.

Much of what looks like rudeness in hacker circles is not intended to give
offence. Rather, it's the product of the direct, cut-through-the-bullshit
communications style that is natural to people who are more concerned about
solving problems than making others feel warm and fuzzy.
