-.SH DESCRIPTION
-.sp
-.LP
-\fBmemcached\fR is a flexible memory object caching daemon
-designed to alleviate database load in dynamic web applications by storing
-objects in memory.  It is based on \fBlibevent\fR to scale to
-any size needed, and is specifically optimized to avoid swapping and always
-use non-blocking I/O. This man page documents briefly the \fBmemcached\fR memory
-object caching daemon.

-.SH PACKAGE CONTENTS
-.sp
-.LP
-The \fBmemcached\fR package consists of the memcached server and
-man pages for the server. 
-.sp
-.LP
-Client libraries can be made available by installing other packages.
-.sp
-.LP
-The memcached server is based on the memcached open-source software
-available from http://www.danga.com/memcached/\&.
-.SH SECURITY
-.sp
-.LP
-When the memcached server is started, it listens for network requests
-on a TCP port and/or a UDP port. It is important for the security of the network
-that you protect this port, for example, by blocking access to this port in
-a firewall. 
-.sp
-.LP
-The default TCP port number to use is 11211. 
-.sp
-.LP
-You may use the \fB-p\fR option to set another TCP port number.
-There is no default UDP port number. You can use the \fB-U\fR option
-to set a UDP port number.
-.sp
-.LP
-If you are running memcached on a server with multiple network interfaces,
-you can restrict vulnerability by binding memcached to a single interface
-by using the \fB-l\fR option.
-.LP
-Caution - 
-.sp
-.RS 2
-Note that \fBmemcached\fR was designed for speed
-and not for security. There is no authentication of requests that go in to
-the memcached servers, and communication is not encrypted. The network that
-your memcached servers and clients run within should be safe-guarded against
-network attacks.
