[Note:  this is a VMS DCL shar file, but not the fancy kind.  ++bsa]

This program was written because we needed a quick way to find out
what users had a certain privilege.  You just tell the program what
privilege(s) you are interested in, and it will tell you who has
them.  Note that you have to have certain privileges to run this program.

This was written in VAX Pascal, version 3.6 under VMS version 4.7 .

PROGRAM Get_Privileges (INPUT, OUTPUT, OutFile);

   This program takes as input a list of privileges and produces as output
   an alphabetical list of the users who have those privileges.
