Columbia AppleTalk Package
     
        (CAP) An implementation of {Apple Computer}'s {AppleTalk}
        {protocol}s for {Unix} {4.2BSD} and its derivatives, from
        {Columbia University}.  There are two different {LAP} delivery
        mechanisms for: {IPTalk} and {Ethertalk} (possibly using
        {UAB}).
     
        CAP supports the following {AppleTalk} {protocol}s: {AppleTalk
        Transaction Protocol} (ATP), {Name Binding Protocol} (NBP),
        {Printer Access Protocol} (PAP), {AppleTalk Session Protocol}
        (ASP), {AppleTalk Filing Protocol} (AFP) client side.  In
        addition, the {Datagram Delivery Protocol} (DDP) and {Zone
        Information Protocol} (ZIP) are partially available.  The
        structure of the {Internet Appletalk Bridge} software makes it
        impossible to provide full DDP service.  Only the Get Zone
        List ATP ZIP command is implemented for ZIP.
