                                       MIME PARSER

   The MIME parser stream presents a MIME document.  It recursively invokes the
   format manager to handle embedded formats.

   As well as stripping off and parsing the headers, the MIME parser has to
   parse any weirld MIME encodings it may meet within the body parts of
   messages, and must deal with multipart messages.

   This module is implemented to the level necessary for operation with WWW,
   but is not currently complete for any arbitrary MIME message.

   Check the source for latest additions to functionality.

   The MIME parser is complicated by the fact that WWW allows real binary to be
   sent, not ASCII encoded.  Therefore the netascii decoding is included in
   this module.  One cannot layer it by converting first from Net to local
   text, then decoding it.  Of course, for local files, the net ascii decoding
   is not needed.  There are therefore two creation routines.
