a question about loginfo & commit emails

[Isaac Claymore]

Folks, I'm planning to set up CVSROOT/loginfo to deliver
commit emails. After reading 'info cvs', I found that 
cvs provides stuffs like %svV to access file name and
revision information of a commit operation. I'd love to
include the log message, i.e. what '-m' specifies in a 
'cvs commit', in commit mails, but cannot figure out
how to retrieve that information.
Have I missed anything? Or, is there any other trick?
Thanks.
