 		<h1>NewtonScript</h1>
 		<p><em>NewtonScript</em> is an object-oriented programming language developed by <a href="http://waltersmith.us/">Walter Smith</a> for <a href="http://www.apple.com/">Apple</a> for the Newton OS running on their MessagePad &amp; eMate hardware. It borrows concepts from the Smalltalk, LISP, and Self programming languages with special consideration for a low memory footprint (esp. differential inheritance). In 2003 a NewtonScript interpreter, <a href="#newt0">NEWT/0</a> was developed by Makoto Nukui allowing for its use on other platforms.</p>
