TOOLS ROUNDUP! TOOLS ROUNDUP!

[Mike Kerner]

I'm still thinking about sessions for LCG.  One of the suggestions I had
seen was an intro on tool x.  How about a tools roundup?  Names and URL's
for your favorite LC tools go in this thread, please.  More is better so I
don't leave anyone out.

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
