xwall
     NAME
          xwall - send a message to X display
     SYNOPSIS
          xwall [-display display] [-user user] [-timeout timeout]
     DESCRIPTION
          The xwall program reads its standard input until an EOF.  It
          then sends this message to the X display.
     OPTIONS
          The xwall program accepts the following options:
          -display display
                  This option gives the name of the X display where
                  the message should appear.  If not specified, the
                  ``DISPLAY'' environment variable is used.
          -timeout timeout
                  This option sets the time in seconds that xwall
                  waits before deciding that it cannot deliver the
                  message.  The default value is 15 seconds.
          -user user
                  This option causes xwall to assume the identity of
                  the named user.  This allows xwall to connect with
                  an X display that is running user level
                  authorization.
