was a graphical user interface
library and application programming interface
(API) created by Sun
in an attempt to make a compromise between the two competing look-and-feels for UNIX
workstations at the time -- OpenLook
and OSF Motif
The library provided common GUI features such as boxes, menus, lists, buttons, etc., but allowed users to choose which GUI they wanted at runtime. It was a short lived project, as the industry was solidly moving towards Motif as the standard.
