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.
