Xw is nice, but it doesn't work with X11R4.  I believe that the version
on the X11R4 tape is not supported by anyone officially or
unofficially.  HP is now shipping Motif with its hardware.

The latest edition of this book uses Motif examples.

HP's 3D look went into Motif.

The semantics of XView are similar to those of the X Toolkit.  There
are some advantages to XView, such as more UNIX-specific support.
Disadvantages of XView are incompatibility with X Toolkit widgets, no
subclassing, no separation between "intrinsics" and "widgets", and no
support for popular X Toolkit user interfaces such as configuration
through translation management and resource management.  Also, some
customers are now requiring (to some degree) their purchases to be
based on the X Toolkit (e.g., the recent U.S. Government FIPS).
