-- sfive - spreadspace streaming statistics suite is a generic
-- statistic collection tool for streaming server infrastuctures.
-- The system collects and stores meta data like number of views
-- and throughput from a number of streaming servers and stores
-- it in a global data store.
-- The data acquisition is designed to be generic and extensible in
-- order to support different streaming software.
-- sfive also contains tools and applications to filter and visualize
-- live and recorded data.
