How Much Variable Memory is Being Used

I understand that the Arduino has a limit of 2K bytes of variable memory.

Is there a way to tell from the Arduino IDE how much variable memory is being used by a sketch?

I assume that the included libraries also use some of this memory.

Is there a utility to find this? Do I have to count by brute force?

maybe this helps http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1213583720;start=all

Thanks. That thread describes my program architecture and some of the flaky operation I have been seeing as it grew in size.

Much of the solution seems to involve moving constant strings to PROGMEM. I am reading up on this to see how to do it.
