-  deploycrt self installs the certificates using self signed csr in /opt/zimbra/ssl/zimbra/server
-  deploycrt comm installs the certificates using commercially signed certificate in /opt/zimbra/ssl/zimbra/commercial
-  verifycrt <self|comm> compares openssl md5 [priv_key] and [certfile].
-  migrate moves certs/keys from ZCS installs prior to version 5.0.x
-  addcacert appends an otherwise untrusted ssl certificate to the cacerts file.
     This is primarily for allowance of untrusted ssl certificates in external data sources.
