-ASCIIMathML.js
-==============
-This file contains JavaScript functions to convert ASCII math notation
-and LaTeX to Presentation MathML. Simple graphics commands are also
-translated to SVG images. The conversion is done while the (X)HTML
-page loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
-Explorer 6/7 + MathPlayer (http://www.dessci.com/en/products/mathplayer/) +
-Adobe SVGview 3.03 (http://www.adobe.com/svg/viewer/install/).
-
-Just add the next line to your (X)HTML page with this file in the same folder:
-
-<script type="text/javascript" src="ASCIIMathML.js"></script>
-
-(using the graphics in IE also requires the file "d.svg" in the same folder).
-This is a convenient and inexpensive solution for authoring MathML and SVG.
-
-Version 2.0.9 Nov 3, 2007, (c) Peter Jipsen http://www.chapman.edu/~jipsen
-This version extends ASCIIMathML.js with LaTeXMathML.js and ASCIIsvg.js.
-Latest version at http://www.chapman.edu/~jipsen/mathml/ASCIIMathML.js
-If you use it on a webpage, please send the URL to jipsen@chapman.edu
-
-The LaTeXMathML modifications were made by Douglas Woodall, June 2006.
-(for details see header on the LaTeXMathML part in middle of file)
-Extensive clean-up and improvements by Paulo Soares, Oct 2007.

-Version 1.1, July 20, 2007 (c) modifications by Peter Jipsen
-
-(changes: renamed global variables from AM... to LM... so that
-LaTeXMathML and ASCIIMathML can be used simultaneously)
-
-Previous header notice:
-This file (Version 1.0), is due to Douglas Woodall, June 2006.
-It contains JavaScript functions to convert (most simple) LaTeX
-math notation to Presentation MathML. It was obtained by
-downloading the file ASCIIMathML.js from
- http://www1.chapman.edu/~jipsen/mathml/asciimathdownload/
-and modifying it so that it carries out ONLY those conversions
-that would be carried out in LaTeX. A description of the original
-file, with examples, can be found at
- www1.chapman.edu/~jipsen/mathml/asciimath.html
- ASCIIMathML: Math on the web for everyone
-
-Here is the header notice from the original file:
-
-ASCIIMathML.js
-==============
-This file contains JavaScript functions to convert ASCII math notation
-to Presentation MathML. The conversion is done while the (X)HTML page
-loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
-Explorer 6+MathPlayer (http://www.dessci.com/en/products/mathplayer/).
-Just add the next line to your (X)HTML page with this file in the same folder:
-<script type="text/javascript" src="ASCIIMathML.js"></script>
-This is a convenient and inexpensive solution for authoring MathML.
-
-Version 1.4.7 Dec 15, 2005, (c) Peter Jipsen http://www.chapman.edu/~jipsen

-/* ASCIIsvg.js
-==============
-JavaScript routines to dynamically generate Scalable Vector Graphics
-using a mathematical xy-coordinate system (y increases upwards) and
-very intuitive JavaScript commands (no programming experience required).
-ASCIIsvg.js is good for learning math and illustrating online math texts.
-Works with Internet Explorer+Adobe SVGviewer and SVG enabled Mozilla/Firefox.
