<p class=parameters>
For a simple message, all that is needed is a set of <tt>headers</tt>
and the <tt>body</tt>. The message <tt>body</tt> can be given as a string
or as a <em>simple</em>
<a href="http://lua-users.org/wiki/FiltersSourcesAndSinks">LTN12</a>
source. For multipart messages, the body is a table that
recursively defines each part as an independent message, plus an optional
<tt>preamble</tt> and <tt>epilogue</tt>.
</p>
<p class=return>
The function returns a <em>simple</em>
<a href="http://lua-users.org/wiki/FiltersSourcesAndSinks">LTN12</a>
source that produces the
message contents as defined by <tt>mesgt</tt>, chunk by chunk.
Hopefully, the following
example will make things clear. When in doubt, refer to the appropriate RFC
as listed in the introduction. </p>
