+     "Frei0r is a minimalistic plugin API for video effects.
+The main emphasis is on simplicity for an API that will round up
+the most common video effects into simple filters, sources and
+mixers that can be controlled by parameters.  Frei0r wants to
+provide a way to share these simple effects between many
+applications, avoiding their reimplementation by different projects.
+It counts more than 100 plugins.")
