-- Command: label LEFT/S, CENTER/S, SINGLE/S, DOUBLE/S, LABEL/A/F
     This object is a simple label that can be used in conjunction with
     another object for clarification of the other objects purpose.

        * LEFT [I..] - this switch will force the label to be left
          justified.

        * CENTER [I..] - this switch will force the label to be
          centered.

        * SINGLE [I..] - this switch will cause extra vertical space to
          be added to the label to center it about the same space
          occupied by an object with a single width frame.

        * DOUBLE [I..] - this switch will cause extra vertical space to
          be added to the label to center it about the same space
          occupied by an object with a double width frame.

        * LABEL [I..] - this is the text for the label (which must be
          the last argument and may contain spaces).

     Example use of this command:

          window
              .
              .
              .
