+    """The purpose of this project is to provide a simple and
+    reliable ffmpeg wrapper for working with video files. It
+    implements two simple generator functions for reading and
+    writing data from/to ffmpeg, which reliably terminate the
+    ffmpeg process when done. It also takes care of publishing
+    platform-specific wheels that include the binary ffmpeg
+    executables."""
