+Kate is a free codec for text based data, which can also carry images.
+It is typically used to create overlays on a video.
+
+libkate, a codec for Kate streams, is required to build this plugin:
+http://libkate.googlecode.com/
+
+libtiger, a rendering library for Kate streams, is optional:
+http://libtiger.googlecode.com/
+
+The Kate plugin contains various elements to manipulate Kate streams:
+
+ - katedec: decodes Kate streams to text
+ - kateenc: encodes Kate streams from text and SPU images
+ - kateparse: parses Kate streams
+ - katetag: allows changing metadata in Kate streams
+ - tiger: decodes and renders Kate streams using libtiger (needs libtiger)
+
+More information about Kate can be found at:
+http://wiki.xiph.org/index.php/OggKate

+ * @short_description: parses kate streams
+ * @see_also: katedec, vorbisparse, oggdemux, theoraparse
+ *
+ * <refsect2>
+ * <para>
+ * The kateparse element will parse the header packets of the Kate
+ * stream and put them as the streamheader in the caps. This is used in the
+ * multifdsink case where you want to stream live kate streams to multiple
+ * clients, each client has to receive the streamheaders first before they can
+ * consume the kate packets.
+ * </para>
+ * <para>
+ * This element also makes sure that the buffers that it pushes out are properly
+ * timestamped and that their offset and offset_end are set. The buffers that
+ * kateparse outputs have all of the metadata that oggmux expects to receive,
+ * which allows you to (for example) remux an ogg/kate file.
+ * </para>
+ * <title>Example pipelines</title>
+ * <para>
+ * <programlisting>
+ * gst-launch -v filesrc location=kate.ogg ! oggdemux ! kateparse ! fakesink
+ * </programlisting>
+ * This pipeline shows that the streamheader is set in the caps, and that each
+ * buffer has the timestamp, duration, offset, and offset_end set.
+ * </para>
+ * <para>
+ * <programlisting>
+ * gst-launch filesrc location=kate.ogg ! oggdemux ! kateparse \
+ * ! oggmux ! filesink location=kate-remuxed.ogg

+ * This pipeline shows remuxing. kate-remuxed.ogg might not be exactly the same
+ * as kate.ogg, but they should produce exactly the same decoded data.

+ * SECTION:element-katetag
+ * @see_also: #oggdemux, #oggmux, #kateparse, #GstTagSetter
+ * @short_description: retags kate streams
+ *
+ * <refsect2>
+ * <para>
+ * The katetag element can change the tag contained within a raw
+ * kate stream. Specifically, it modifies the comments header packet
+ * of the kate stream, as well as the language and category of the
+ * kate stream.
+ * </para>
+ * <para>
+ * The element will also process the stream as the #kateparse element does
+ * so it can be used when remuxing an Ogg Kate stream, without additional
+ * elements.
+ * </para>
+ * <para>
+ * Applications can set the tags to write using the #GstTagSetter interface.
+ * Tags contained within the kate stream will be picked up
+ * automatically (and merged according to the merge mode set via the tag
+ * setter interface).
+ * </para>
+ * <title>Example pipelines</title>
+ * <para>
+ * This element is only useful with gst-launch for modifying the language
+ * and/or category (which are properties of the stream located in the kate
+ * beginning of stream header), because it does not support setting the tags
+ * on a #GstTagSetter interface. Conceptually, the element will usually be
+ * used like:
+ * <programlisting>
+ * gst-launch -v filesrc location=foo.ogg ! oggdemux ! katetag ! oggmux ! filesink location=bar.ogg
+ * </programlisting>
+ * </para>
+ * <para>
+ * This pipeline will set the language and category of the stream to the
+ * given values:
+ * <programlisting>
+ * gst-launch -v filesrc location=foo.ogg ! oggdemux ! katetag language=pt_BR category=subtitles ! oggmux ! filesink location=bar.ogg
+ * </programlisting>
+ * </para>
