# description:	Squid - Internet Object Cache. Internet object caching is \
# 		a way to store requested Internet objects (i.e., data \
# 		available via the HTTP, FTP, and gopher protocols) on a \
# 		system closer to the requesting site than to the source. \
#		Web browsers can then use the local Squid cache as a proxy \
#		HTTP server, reducing access time as well as bandwidth \
#		consumption.
