  13 # update-pwd-db file [user]

  15 #   file - always passed.  This is the full path to the
  16 #          file that is about to become the new etc/passwd
  17 #          file.  It will be renamed into place after this
  18 #          script returns successfully.
  19 #
  20 #   user - optionally passed.  If passed then the only
  21 #          change to file involves the username 'user'.
