+   <p><code>Registry</code> is a container for a related set of meta data.</p>
+
+   <p>Various pieces of ad-hoc information need to be retained within Blitz.
+   Chances are that some of this information belongs in a logical group hence
+   we allow for creation of more than one <code>Registry</code> each of which is identified
+   by a unique name. <P>
+
+   <p>Just like all the other storage within Blitz, the content of <code>Registry</code>
+   instances has to be kept sync'd (the user may also generate log information
+   depending on whether they choose to in-line update or log and sync). Thus,
+   most users of <code>Registry</code> will implement <code>Syncable</code>.
+   </p>
+
+   <p>All modifications to <code>Registry</code> content are achieved through
+   a <code>RegistryAccessor</code>.
