<DIV><FONT face=Arial size=2>We have recognized and addressed this issue for our
GME-based product CAPE. During installation, we distribute and register
all paradigm versions that we currently support, and updaters are provided to
address any discontinuities not handled by GME's native upgrading
features. We do this because it is an unreasonable expectation of our
users to export all of their GME projects to XME prior to upgrading GME
versions, especially when exporting to XME is used to address simply
the unavailability of earlier versions of a paradigm.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>GME distributes several paradigms as part of its
installation. Most important among these is the MetaGME paradigm that is
an essential part of using GME for anything other than projects that
use the other distributed paradigms. It would be relatively
straightforward for the MetaGME paradigm to follow the lead of CAPE in
supporting migration between paradigm versions, since it is unlikely for
this paradigm to incorporate such discontinuties as could not be handled by
GME's native upgrading features or simple updaters.</FONT></DIV>
