Gifsicle is a command-line program for manipulating GIF image files. It has good support for transparency and colormap manipulation, simple image transformations (cropping, flipping), and creating, deconstructing, and editing GIF animations. It also optimizes GIF animations for space. The package also includes 'gifview,' an animated-GIF viewer which can show animations as slideshows or in real time, and 'gifdiff,' which compares two GIFs for identical visual appearance.
