CDE is the major result of the Cose agreement. It is a set of tools and window toolkits
(Motif 1.2.3), along with supporting cross-process communications software (ToolTalk®),
which will form the basis of the window offerings of all major UNIX vendors. Each
vendor will productize CDE in its own fashion and ultimately maintain separate source
bases, doing its own value-add and its own bug fixing.

vendors including DEC and HP, while Sun has stayed with ONC+TM. As part of the Cose
agreement, all of the vendors will support both DCE and ONC+.
