#
# 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.
