 .IP "--capath <CA certificate directory>"
 (SSL) Tells curl to use the specified certificate directory to verify the
-peer. The certificates must be in PEM format, and if curl is built against
-OpenSSL, the directory must have been processed using the c_rehash utility
-supplied with OpenSSL. Using \fI--capath\fP can allow OpenSSL-powered curl to
-make SSL-connections much more efficiently than using \fI--cacert\fP if the
-\fI--cacert\fP file contains many CA certificates.
