Itex2mml is a software tool that transforms embedded Itex (a dialect if latex) into XHTML and MathML.
Itex is the way of describing math, including subscripts, superscripts, Greek letter and all other math symbols using only the standard characters available on a keyboard. eg 2^2 = 2 to the power of 2. There are a variety of web browsers out there that can understand, read and render Itex. One such browser is Mozilla.
