-Icecast protocol
+Icecast protocol (stream to Icecast servers)
+
+This protocol accepts the following options:
 
 @table @option
 @item ice_genre
-Set the genre of the stream.
+Set the stream genre.
 
 @item ice_name
-Set the name of the stream.
+Set the stream name.
 
 @item ice_description
-Set the description of the stream.
+Set the stream description.
 
 @item ice_url
-Set the stream website url.
+Set the stream website URL.
 
 @item ice_public
 Set if the stream should be public.
-Default is 0 (not public).
-
-@item ice_password
-Password for the mountpoint.
-
-@item legacy_icecast
-If set to 1, enable support for legacy Icecast (Version < 2.4), using the SOURCE method
-instead of the PUT method.
-
-@item content_type
-Set a specific content type for the stream.
-This MUST be set if streaming else than audio/mpeg
+The default is 0 (not public).
 
 @item user_agent
-Override the User-Agent header. If not specified the protocol will use a
-string describing the libavformat build. ("Lavf/<version>")
+Override the User-Agent header. If not specified a string of the form
+"Lavf/<version>" will be used.
+
+@item password
+Set the Icecast mountpoint password.
+
+@item content_type
+Set the stream content type. This must be set if it is different from
+audio/mpeg.
+
+@item legacy_icecast
+This enables support for Icecast versions < 2.4.0, that do not support the
+HTTP PUT method but the SOURCE method.
