📝 NOTES

🎀 PROGRAM PREFIX

okay so 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 that case, the client programs of libmemcached-awesome would be called mccat, mccp, etc. respectively. 💅
