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.
