/*
 * ULTRIX program that acts as a front end to a decnet gateway 
 * for decnet ls (dls).  The point of the shell is to make the Ultrix-11 
 * user think he is using decnet dls to see the contents of a remote dir.
 * User interface here is the same as with dls.  The program uses rsh 
 * to transfer the command to the gateway where dls is actually run. 
 * Ultrix-11 does not have decnet. 
 *
 * Creation date - 10 March, 1985, u.s.
