+     "PyAV is a Python library that allows for direct and precise manipulation
+of media through containers, streams, packets, codecs, and frames.  It provides
+access to the powerful FFmpeg libraries while managing the complex details as
+much as possible.
+PyAV also facilitates data transformation and integration with
+other packages such as Numpy and Pillow.  However, working with media is a
+challenging task and PyAV cannot abstract it away or make all the best decisions
+for you.  If you can accomplish your tasks with the ffmpeg command, PyAV may not
+be necessary.  Nonetheless, PyAV is an essential tool when working with media
+that requires its specific capabilities.")
