I ftp'ed to moon to copy grass4.0 and discovered that it only existed in 11 separate files, grassaa-grassak (rather than grass4.0.cpio.Z). How does this work? After ftp'ing these as binary files, do I then concatenate them into a single file named 'grass4.0.cpio.Z', uncompress this, then unarchive the uncompressed file with cpio?
