* jsMath: Mathematics on the Web

|
|
* This jsMath package makes it possible to display mathematics in HTML pages
|
|
* that are viewable by a wide range of browsers on both the Mac and the IBM PC,
|
|
* including browsers that don't process MathML. See
|
|
*
|
|
* http://www.math.union.edu/locate/jsMath
|
|
*
|
|
* for the latest version, and for documentation on how to use jsMath.

* The basic macros for plain TeX.

|
|
* When the control sequence on the left is called, the JavaScript

* funtion on the right is called, with the name of the control sequence
|
|
* as its first parameter (this way, the same function can be called by
|
|
* several different control sequences to do similar actions, and the
|
|
* function can still tell which TeX command was issued). If the right

* is an array, the first entry is the routine to call, and the
|
|
* remaining entries in the array are parameters to pass to the function
|
|
* as the second parameter (they are in an array reference).
