gifsicle-neo

Fork notice: This is a maintained fork of the original gifsicle-bin package. The original package is no longer actively updated. This fork includes several improvements and modernizations.

gifsicle manipulates GIF image files in many different ways. Depending on command line options, it can merge several GIFs into a GIF animation; explode an animation into its component frames; change individual frames in an animation; turn interlacing on and off; add transparency and much more.

You probably want imagemin-gifsicle or psimage instead.
