OpenLook is a graphical user interface specification.  (AT&T, in their
infinite wisdom, decided to call their toolkit, which implements the
OpenLook spec., OpenLook.)  This is the look and feel part of
OpenWindows.

OpenWindows is a window based user environment.  It's the X11/NeWS
server, the Deskset tools (i.e. cmdtool, filemanager, mailtool), and
the user-interface toolkits (XView, OLIT, and tNt).

XView (X Window-System-based Visual/Integrated Environment for
Workstations (I swear I'm didn't make that up :-)) is based directly on
Xlib.

OLIT (OpenLook Intrinsics Toolkit) is an intrinsics based toolkit.

tNt (the NeWS toolkit) is a NeWS based toolkit.  NeWS is
object-oriented PostScript with windowing capabilities added.

All three toolkits implement the OpenLook graphical user interface,
although the version of tNt in OpenWindows 2.0 does not provide the 3D
look.

DISCLAIMER:  I'm not in marketing.  This is not an official Sun
statement.  In fact, I may have no idea at all of what I'm talking
about.
