I think it is *the* most useful command.

1.  Profile sessions -- you get 100 percent of your program's effort churning
away even on a single CPU machine.  You can figure out where the hotspots are
much better.

2. Analysis -- If you give a program long time control, set up a position, and
let it run in auto mode, it will give you a far, far better pv to work from than
sitting on the same spot for the same time frame.

Here is the PGN standard, from Heiner's page (it popped up first in the search
for some reason):
http://www.drb.insel.de/~heiner/Chess/PGN_Standard.txt
Look at section 16.2.

Also, Crafty has a fancy-pants EPD processor written by SJE himself.
Beowulf has a public source EPD processor section.
Sjeng has a public source EPD processor section.

Lots of other engines have EPD processing.  It is important to both read and
write EPD.
