/*   mimefilt.c --- test harness for libmime.a
     Created: Jamie Zawinski <jwz@netscape.com>, 15-May-96.

   This program reads a message from stdin and writes the output of the MIME
   parser on stdout.

   Parameters can be passed to the parser through the usual URL mechanism:

     mimefilt BASE-URL?headers=all&rot13 < in > out

   Some parameters can't be affected that way, so some additional switches
   may be passed on the command line after the URL:

     -fancy		whether fancy headers should be generated (default)

     -no-fancy	opposite; this uses the headers used in the cases of
				FO_SAVE_AS_TEXT or FO_QUOTE_MESSAGE

     -html		whether we should convert to HTML (like FO_PRESENT);
				this is the default if no ?part= is specified.

     -raw		don't convert to HTML (FO_SAVE_AS);
				this is the default if a ?part= is specified.

     -outline	at the end, print a debugging overview of the MIME structure

   Before any output comes a blurb listing the content-type, charset, and 
   various other info that would have been put in the generated URL struct.
   It's printed to the beginning of the output because otherwise this out-
   of-band data would have been lost.  (So the output of this program is,
   in fact, a raw HTTP response.)
