    (description
     "ImageMagick® is a software suite to create, edit, compose, or convert
bitmap images. It can read and write images in a variety of formats (over 100)
including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG,
and TIFF. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and
transform images, adjust image colors, apply various special effects, or draw
text, lines, polygons, ellipses and Bézier curves.")
