* 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.
*
* The structure of the format string is described here:
