+.B ssh\-proxycommand [--no-connect] HOST [PORT]
+An ssh ProxyCommand that can be used to trigger a monkeysphere update
+of the ssh known_hosts file for a host that is being connected to with
+ssh. This works by updating the known_hosts file for the host first,
+before an attempted connection to the host is made. Once the
+known_hosts file has been updated, a TCP connection to the host is
+made by exec'ing netcat(1). Regular ssh communication is then done
+over this netcat TCP connection (see ProxyCommand in ssh_config(5) for
+more info).
+
+This command is meant to be run as the ssh "ProxyCommand". This can
+either be done by specifying the proxy command on the command line:
+
+.B ssh \-o ProxyCommand="monkeysphere ssh\-proxycommand %h %p" ...
+
+or by adding the following line to your ~/.ssh/config script:
+
+.B ProxyCommand monkeysphere ssh\-proxycommand %h %p
+
+The script can easily be incorporated into other ProxyCommand scripts
+by calling it with the "\-\-no\-connect" option, i.e.:
+
+.B monkeysphere ssh\-proxycommand \-\-no\-connect "$HOST" "$PORT"
+
+This will run everything except the final exec of netcat to make the
+TCP connection to the host. In this way this command can be added to
+another proxy command that does other stuff, and then makes the
+connection to the host itself.
+
+KEYSERVER CHECKING:
+The proxy command has a fairly nuanced policy for when keyservers are
+queried when processing a host. If the host userID is not found in
+either the user's keyring or in the known_hosts file, then the
+keyserver is queried for the host userID. If the host userID is found
+in the user's keyring, then the keyserver is not checked. This
+assumes that the keyring is kept up-to-date, in a cronjob or the like,
+so that revocations are properly handled. If the host userID is not
+found in the user's keyring, but the host is listed in the known_hosts
+file, then the keyserver is not checked. This last policy might
+change in the future, possibly by adding a deferred check, so that
+hosts that go from non-monkeysphere-enabled to monkeysphere-enabled
+will be properly checked.
+
+Setting the CHECK_KEYSERVER variable in the config file or the
+MONKEYSPHERE_CHECK_KEYSERVER environment variable to either `true' or
+`false' will override the keyserver-checking policy defined above and
+either always or never check the keyserver for host key updates.
