          rotate - rotate or mirror a picture

     SYNOPSIS
          rotate [ -r degree ] [ -u | -l ] [ file ]

     DESCRIPTION
          Rotate reads its input image (default from standard input),
          applies the rotation or mirroring and outputs the trans-
          formed image in compressed plan9 bitmap format.

          The option -r rotates the image clockwise in 90 degree steps
