memcached is a general-purpose distributed memory caching system
originally developed by Danga Interactive for LiveJournal but now used
by many other sites. It is often used to speed up dynamic
database-driven websites by caching data and objects in RAM to reduce
the number of times an external data source (such as a database or API)
must be read. Here we describe the options available from the command
line to control a memcached instance via unix socket or IP:port.
