What is Motif (LessTif)?

Throughout the Grace docs, saying “M*tif” we actually refer to the M*tif API, defining a set of functions for building graphical user interfaces (GUI) via numerous widgets (buttons, labels, etc). Grace makes a heavy use of the M*tif API. There are several implementations of the interface. The original OSF Motif (see http://www.opengroup.org) recently changed its license: on open-source platforms you may have a chance to use it for free, although it’s not in general qualified as either a FreeSource or OpenSource product. There is, however, a free replacement for Motif called LessTif (see http://www.lesstif.org). LessTif is intended to be a 100% source compatible replacement for Motif, but is still under development. For the purposes of Grace, try using the latest version of LessTif (at least 0.92.6 and above). The LessTif people usually receive many bug reports from the Grace developers, so you might hope that a few remaining bugs in LessTif will be fixed rather quickly.
