+.SS Sequence File Format
+The sequence file format is based on the RFC\-5322 message format.  Each line
+of the sequence file corresponds to one sequence.  The line starts with the
+sequence name followed by a `:', then followed by a space-separated list of message numbers
+that correspond to messages that are part of the named sequence.  A contiguous
