pkg

The file extension used to identify Newton package files. Confusingly, a number of other operating systems including Solaris, BeOS, Mac OS X, and iOS also use the .pkg extension to denote installable software packages. To avoid interoperability issues, it has been suggested that Newton package files use the .newtonpkg file extension on current operating systems.
