Actually, `unify_uids' is the name of the whole package, which includes
two programs called `mp' and `zap'.  mp takes one `special' passwd file,
N `regular' passwd files, and produces N new passwd files with unified
uids and gids, along with N `map' files.  zap applies one of these map
files to the disk.  The special file assigns particular IDs, such as
`root = 0'; people not in the special file get IDs starting at 256 (or
some other value of your choice).

The package also includes a few programs for fixing up quota files and
such.  I wrote mp and zap, others wrote the others.
