Motif is the freely available source code distribution for the Motif
user interface component toolkit. Motif is built on top of the standard
X Toolkit(Xt) and X11 libraries.
This the first motif version that is released under LGPL v2.1.
Postscript and PDF Documents (users guides and reference manuals) could be
downloaded at: http://www.opengroup.org/openmotif/docs/
This conflicts with the lesstif package that comes with Slackware; in other
words, only one should be installed at any given time. You will need to
recompile xpdf and any lesstif-dependent packages if you encounter problems
running them after installing motif.
