"Motif is quite a collection of code. For those of you who need
a ramp-up, Motif is a X Window interface. It came to exist because
commercial vendors (like IBM and H-P) wanted a uniform interface
based on X. (The creators of X did not envision X as being its own
interface: the mantra at the X Consortium was that X be a set of
tools so that others could create their own graphical interfaces.
Which they are doing to this day -- witness GNOME and KDE, which
are both X-based.)"
"Basically, Motif is based on the X Window libraries, but Motif
adds its own toolkit ("widgets"), a style guide, and a window
manager, mwm. All three combine to create a look and feel, and
Motif ended up being the basis for the Common Desktop
"From the beginning Motif was a commercial endeavor, eventually
controlled by the Open (really Closed) Group. On May 15 of this
year, the Open Group did something new: it released the source code
for Motif, now called OpenMotif, under the Open Group Public
License. Basically, this license allowed those using Open Source
operating systems -- i.e., Linux and BSD -- to use Motif. As the
FAQ page says:"
"'The Open Group Public License for Motif grants rights only to
use the software on or with operating systems that are themselves
Open Source programs. In restricting the applicability of the
license to Open Source platforms this does not meet term 8 of the
Open Software Definition.'"
