openstep
     
         an object-oriented application
        programming interface api derived from nextstep and
        proposed as an open standard by next in 1994.
     
        openstep is the specification of the object kits of nextstep.
        openstep/mach was an implementation of this specification.
        the original, openstep version 4.0, and really was nextstep 4.
        rhapsody was the codename for apple's mac os x server,
        which is really nextstep 5 it calls itself "kernel 5.3" at
        boot time.
     
        openstep was designed to be implemented independently of the
        computer's operating system, hardware, and user interface.
        the api for rhapsody will be a superset of openstep's.
     
        when the openstep api is implemented for a specific platform
        and made into a product, it is written in uppercase,
        e.g. openstep developer 4.2 for mach, or openstep enterprise
        for windows nt and windows 95.  versions of openstep exist
        for windows 95/nt, solaris, hp/ux, and mach.
