.SH DESCRIPTION
.sp
"Memcached is a high\-performance, distributed memory object caching
applications by alleviating database load." \fI\%http://danga.com/memcached/\fP
.sp
\fBlibmemcached\fP is a small, thread\-safe client library for the
-memcached protocol. The code has all been written with an eye to allow
+memcached protocol. The code has all been written to allow
for both web and embedded usage. It handles the work behind routing
-particular keys to specific servers that you specify (and values are
-matched based on server order as supplied by you). It implements both
-a modula and consistent method of object distribution.
+individual keys to specific servers specified by the developer (and values are
+matched based on server order as supplied by the user). It implements
+a modular and consistent method of object distribution.
.sp
There are multiple implemented routing and hashing methods. See the
-memcached_behavior_set() manpage.
+memcached_behavior_set() manpage for more information.
.sp
All operations are performed against a \fBmemcached_st\fP structure.
These structures can either be dynamically allocated or statically
Nearly all functions return a \fBmemcached_return_t\fP value.
This value can be translated to a printable string with memcached_strerror(3).
.sp
-Partitioning based on keys is supported in the library. Using the key partioning
-functions it is possible to group sets of object onto servers.
+Objects are stored on servers by hashing keys. The hash value maps the key to a particular server. All clients understand how this hashing works, so it is possibly to reliably both push data to a server and retrieve data from a server.
+.sp
+Group keys can be optionally used to group sets of objects with servers.
+.sp
+Namespaces are supported, and can be used to partition caches so that multiple applications can use the same memcached servers.
.sp
\fBmemcached_st\fP structures are thread\-safe, but each thread must
contain its own structure (that is, if you want to share these among
used in this library.
.sp
If you are working with GNU autotools you will want to add the following to
-your configure.ac to properly include libmemcached in your application.
+your COPYING to properly include libmemcached in your application.
