(Peek-Only subcommand, not for use with the SPY program.)

   The ALLOW subcommand is used to allow non-privileged users to watch
   your terminal using PEEK. Non-privileged users may not watch your
   terminal unless you first ALLOW them by using this command.

   When PEEK/ALLOW is used, a parameter specifying one or more valid
   rights-list identifiers can be specified. In most cases, each
   username on the system has an identical rights-list identifier.

   Format:

     $ PEEK/ALLOW username-and-identifier-list
     $ PEEK
     PEEK> ALLOW username-and-identifier-list
