(description "Liboop is a low-level event loop management library for
POSIX-based operating systems. It supports the development of modular,
multiplexed applications which may respond to events from several sources. It
replaces the \"select() loop\" and allows the registration of event handlers
for file and network I/O, timers and signals. Since processes use these
mechanisms for almost all external communication, liboop can be used as the
basis for almost any application.")
