+    You should be able to use any files created by MongoGridFS with any other 
+    drivers, and visa vera.  However, some drivers expect that all metadata
+    associated with a file be in a "metadata" field.  If you're going to be 
+    using other languages, it's a good idea to wrap info you might want them to
+    see in a "metadata" field.  For example, instead of:
+   </para>
+   <programlisting role="php">

+<?php
+
