DESCRIPTION

14       memcached-tool is a Perl script used to print statistics from a running
15       memcached instance.  The first parameter specifies the address  of  the
16       daemon  either  by  a  hostname, optionally followed by the port number
17       (the default is 11211), or a path to UNIX  domain  socket.  The  second
18       parameter specifies the mode in which the tool should run.
