Need Clues: procmail configuration for IETF-Announce

Hello:

For the first time in my life, last weekend I read the fine 
procmail manual. I need some clues on how to configure procmail 
for splitting the IETF-Announce list; especially separating the 
I-D ACTION part. If you have one, would you please send me the 
procmail part of filtering IETF-Announce?
