- * What is a library without an example to show you how to use the library?

- * Please note that this is an exemple on how to use the library, not

- *
- * With that in mind, let me give you some pointers into the source:
- * storage.c/h - Implements the item store for this server and not really
- * interesting for this example.
- * interface_v0.c - Shows an implementation of the memcached server by using
- * the "raw" access to the packets as they arrive
- * interface_v1.c - Shows an implementation of the memcached server by using
- * the more "logical" interface.
- * memcached_light.c - This file sets up all of the sockets and run the main
- * message loop.
- *
- *
- * config.h is included so that I can use the ntohll/htonll on platforms that
- * doesn't have that (this is a private function inside libmemcached, so you
- * cannot use it directly from libmemcached without special modifications to
- * the library)
