+# 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.
