+/* 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.
