(he digs out the Usenix Summer '89 proceedings, and Winter '89 proceedings)

Unfortunately, XVT specifies look & feel and policy (menu bars, text insertion
point is a caret, etc), as well as a program interface. The description of the
X port in the Winter proceedings indicates that the XVT user interface is
pretty much cast in stone.

This, of course, makes it less than ideal as a standard program interface
to use for multiple user interfaces. As I indicated in my original article,
you should not have to do more than change your libraries and run Make to
switch from OpenLook to Motif or GEM or whatever.
