[MOTIF]The [MOTIF] package contains those subroutines and functions that
deal with widgets. Currently, LUX uses the Motif library to
generate widgets, because of its widespread use and availability.
However, this library is not part of LUX itself, but must be obtained
separately from a commercial company. If a viable non-commercial
alternative becomes widely available, and if the authors find the time,
then they may switch to such an alternative.
The [MOTIF] package is contained in the [X11] package.
The [MOTIF] package is included automatically it is detected on
your computer system, and if also the [X11] package is included,
unless you specify the --without-motif option to
./configure.
