<para>
Read "comments" (i.e. key-value pairs) from the file
specified by "URI". This "URI" can be a path relative
to the music directory or a URL in the form
"file:///foo/bar.ogg".
</para>
<para>

Comments with suspicious characters (e.g. newlines) are
ignored silently.
</para>
<para>

decoder plugins support it. For example, on Ogg files,
this lists the Vorbis comments.
