DXR will be turned off on Tuesday, December 29th. It will redirect to Searchfox.
See the announcement on Discourse.

DXR is a code search and navigation tool aimed at making sense of large projects. It supports full-text and regex searches as well as structural queries.

/* 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.
