      The <command>groups</command> command displays the current group names
      or ID values. If the value does not have a corresponding entry in
      <filename>/etc/group</filename>, the value will be displayed as the
      numerical group value. The optional <emphasis
      remap='I'>user</emphasis> parameter will display the groups for the
      named <emphasis remap='I'>user</emphasis>.

      Systems which do not support concurrent group sets will have the
      information from <filename>/etc/group</filename> reported. The user
      must use <command>newgrp</command> or <command>sg</command> to change
      his current real and effective group ID.
