-LaTeXMathML.js
-==============
-
-This file, in this form, 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:
-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
-Latest version at http://www.chapman.edu/~jipsen/mathml/ASCIIMathML.js
-For changes see http://www.chapman.edu/~jipsen/mathml/asciimathchanges.txt
