 .SH "DESCRIPTION"
 .LP 
-\fIgst\-launch\-ext\fP is a tool that is used to run a basic predefined \fIGStreamer\fP pipeline.
+\fIgst\-launch\-ext\fP is a tool that is used to run a basic predefined 
+\fIGStreamer\fP pipeline.  This application is only used as a quick test to 
+ensure proper working of codecs and GStreamer.  It doesn't handle more advanced
+features like synchronisation.
 
 All supported formats in GStreamer should be playable by simply typing:
 
  gst\-launch\-ext filename
 
+It will also print out the pipeline it uses, so you can customize it using
+cut and paste.
+
+.SH "CONFIGURATION"
+.LP 
+\fIgst\-launch\-ext\fP can be configured by creating a .gst file in your
+home directory.  This is a perl-style configuration file and can override
+the defaults for audio and video output sinks.
+
+Here is an example .gst file that implements the same defaults as hard-coded
+in the script :
+
+$cfg{AUDIOSINK} = "osssink";
+$cfg{VIDEOSINK} = "colorspace ! xvideosink";
+
+You can change osssink to any of esdsink, alsasink, jacksink (if you have
+the plug-in), and you can change xvideosink to aasink or sdlvideosink.
+
+Other plug-ins might be used as well if GStreamer has them.
