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?
