NOTES

   PROGRAM PREFIX
       The prefix of this program is variable, i.e. it can be configured at build time.

       Usually  the client programs of libmemcached-awesome are prefixed with mem, like memcat or
       memcp.

       It can be configured, though, to replace the prefix with something else like mc,  in  case
       of  that,  the  client  programs of libmemcached-awesome would be called mccat, mccp, etc.
       respectively.
