+
+    <para>APP is some application-specific information. The
+application can set it itself, and it'll be stored in the JPEG-encoded
+fields (eg; interlacing information for in an AVI or so). COM is the
+same, but it's comments, like 'encoded by me' or so.</para>
+
+    <para>jpeg_markers describes whether the huffman tables,
+quantization tables and the restart interval information (all
+JPEG-specific stuff) should be stored in the JPEG-encoded fields.
+These define how the JPEG field is encoded. If you omit them,
+applications assume you've used standard encoding. You usually do want
+to add them.</para>
