--- This utility is used to make a new version of the Snames package when new
--- names are added to the spec, the existing versions of snames.ads and
--- snames.adb and snames.h are read, and updated to match the set of names in
--- snames.ads. The updated versions are written to snames.ns, snames.nb (new
--- spec/body), and snames.nh (new header file).
