MetroSuction
MetroSuction was a commercial-quality utility for examining and removing support for different hardware architectures in Multiple Architecture Binaries (MABs) or "fat" binaries. "Fat" binaries allowed the same NeXTStep program to run on different types of computers. MetroSuction allowed you to easily see which architectures were supported by a given application and to remove support for a given architecture, freeing up disk space.
