 * AEBuild:
 *
 * AEBuild provides a very high level abstraction for building
 * complete AppleEvents and complex ObjectSpeciers.  Using AEBuild it
 * is easy to produce a textual representation of an AEDesc.  The
 * format is similar to the stdio printf call, where meta data is
 * extracted from a format string and used to build the final
 * representation.
 * 
 * For more information on AEBuild and other APIs in AEHelpers, see:
 *     <http://developer.apple.com/technotes/tn/tn2045.html>

{
   This call lets you augment an existing AppleEvent using the stream
   APIs.  This would be useful, for example, in constructing the reply
   record in an AppleEvent handler.  Note that AEStreamOpenEvent will
   consume the AppleEvent passed in - you can't access it again until the
   stream is closed.  When you're done building the event, AEStreamCloseStream
    will reconstitute it.
