/* 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.)
