/* The MimeUntypedText class is used for untyped message contents, that is,
it is the class used for the body of a message/rfc822 object which had
*no* Content-Type header, as opposed to an unrecognized content-type.
Such a message, technically, does not contain MIME data (it follows only
RFC 822, not RFC 1521.)
This is a container class, and the reason for that is that it loosely
parses the body of the message looking for ``sub-parts'' and then
creates appropriate containers for them.
More specifically, it looks for uuencoded data. It may do more than that
some day.
Basically, the algorithm followed is:
if line is "begin 644 foo.gif"
if there is an open sub-part, close it
add a sub-part with type: image/gif; encoding: x-uue
hand this line to it
and hand subsequent lines to that subpart
else if there is an open uuencoded sub-part, and line is "end"
hand this line to it
close off the uuencoded sub-part
else if there is an open sub-part
hand this line to it
else
open a text/plain subpart
hand this line to it
Adding other types than uuencode to this (for example, PGP) would be
pretty straightforward.
