The seventh and final VOS tutorial demonstrates how to create and use
your own MetaObject extension.  After reading and understanding this
you should be in a good position to understand the workings of many
VOS applications and component libraries, and start writing some code
of your own!  The tutorial is split into four files (in recommendend
reading order):

vostut7hello.hh
  The header file which demonstrates how to subclasses from MetaObject

vostut7hello.cc
  The implementation of the "Hello" class.

vostut7server.cc
  This demonstrates the use of "Hello" as a local metaobject.

vostut7client.cc
  This demonstrates the use of "Hello" as a remote metaobject.
