Tim, hold-off on this at the moment. I want to talk to Matt Caswell
about it to ensure it meets requirements.

Mat is one of the OpenSSL devs. He is very helpful with his comments
and suggestions. In fact, he's the one who alerted me to

What I am wondering is... On a machine where both CAfile and CApath
are working as expected, are we only using CAfile; or are we using
CAPath and getting the CA Zoo if the directory is populated?

CAfile and CApath are names of s_client options that equate to the
parameters in calls like SSL_CTX_load_verify_locations. -CAfile is
actually equivalent to Wget's --ca-certificate. On some distros CApath
is broken so it appears OpenSSL does not trust anything by default.
But this is actually a bug in the utilities.
