Subject: verify ssl cert command line

Sorry about the messed up subject.  I realized it right after I sent 
it.  Anyways, thanks for the advice and I think I can use openssl 
s_client to do what I need, I had considered openssl verify but I'm 
going to have to check a bunch of certs and didn't want to have to deal 
with downloading and storing certs tempararily to check them if possible.

Thanks,
Dave
