          |      'Group'  lists a user's currently active groups or tests for
          |      combinations of groups.  With no  arguments,  'group'  lists
          |      all  of  a  users  currently active groups.  The "-a" option
          |      causes 'group' to return a "1" if all the groups listed  are
          |      active  (i.e.   returns  the logical AND) and '0' otherwise.
          |      The "-o" option causes 'group' to return "1" if any  of  the
          |      listed  groups  are  currently  active  (i.e.   returns  the
          |      logical OR) and a '0' otherwise.   If  a  "<group_list>"  is
          |      specified with no flag argument then 'group' assumes "-a".
