[exim] forwarding based on subject line.

Hello List
I need to forward emails based on the subject line. I just started
this job , today to be exact, so I am not completely sure of the
configuration of the server. I am sure that the mail application is Exim
and that my new employer wants to forward emails based on the subject
line. I have been reading the manual but seeing as it is getting close
to go to work I don't have time to finishing reading.

Thanks in advance.
Sam Garcia.
