======Synopsis:======
__rping__ <server>

======Description:======
This command works like the [[PING]] command ([[CTCP PING]]), except it is used
on a server instead of a client.  As with [[PING]], it is used to test the
relative distance another server is from you across the irc network.

======Restrictions:======
This command is limited to irc operators.  Additionally, it is limited
to the Undernet, and servers using recent ircu server code.
