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.
