Audit logging for gpg-agent

[Ben Edwards]

Hi,

Is there any method for logging which keys have been used and for what 
operations via the agent? Essentially I'd like to be able to tail a file 
or attach to a socket to both send off for safe keeping and also do cute 
things like send a notification with libnotify to inform me that 
something just happened etc. I have tried the agent / scdaemon logs and 
they seem unsuitable for this purpose.

Advice gratefully received,

Ben
