SUMMARY = "A high-performance memory object caching system"
DESCRIPTION = "\
 memcached optimizes specific high-load serving applications that are designed \
 to take advantage of its versatile no-locking memory access system. Clients \
 are available in several different programming languages, to suit the needs \
 of the specific application. Traditionally this has been used in mod_perl \
 apps to avoid storing large chunks of data in Apache memory, and to share \
 this burden across several machines."
