--  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 are read, and updated to match the set of names in snames.ads.
--  The updated versions are written to snames.ns and snames.nb (new spec/body)
