First, a note on consumers. When you start the script, the main menu asks
you to choose a consumer. A consumer is like a viewer, but it could also
write to a stream/file. The "SDL" consumer is the popular Simple DirectMedia
-Layer audio and video output. The "Westley" consumer generates an XML
+Layer audio and video output. The "xml" consumer generates an XML
representation of the service network. That can be played directly due to the
-westley producer plugin. See docs/westley.txt for more information. The
-"MainConcept DV" consumer refers to the proprietary MLT plugin required to
-use MLT with MainConcept DV, DVCPro, and MPEG codecs. "/dev/dv1394/0" refers
-to a device file for transmitting DV over FireWire using the Linux dv1394 kernel
-module. The "BlueFish444" consumer is another proprietary plugin to use
-the BlueFish444 manufactured SDI video/audio output cards with MLT.

+These examples assume the numeric locale LC_NUMERIC decimal separator is a

+running these manually or learning from them, remember to use the appropriate
+separator for your locale.

consumer. The demo also shows the potientional for using and extending the
existing set of services for a full blown news ticker implementation.
