.SH NOTES
.SS PROGRAM PREFIX
.sp
The prefix of this program is variable, i.e. it can be configured at build time.
.sp
Usually the client programs of \fBlibmemcached\-awesome\fP are prefixed with \fBmem\fP, like \fBmemcat\fP or \fBmemcp\fP\&.
.sp
It can be configured, though, to replace the prefix with something else like \fBmc\fP, in case of that,
the client programs of \fBlibmemcached\-awesome\fP would be called \fBmccat\fP, \fBmccp\fP, etc. respectively.
