* extensions/verb.js
|
|
*
|
|
* Part of the jsMath package for mathematics on the web.
|
|
*
|
|
* This file implements the \verb macro. You can activate it
|
|
* by calling
|
|
*
|
|
* jsMath.Extension.Macro('verb');
|
|
*
|
|
* which will cause the extension to be loaded only when it is
|
|
* needed, or you can force it to be loaded via
|
|
*
|
|
* jsMath.Extension.Require('verb');
|
|
*
|
|
* once jsMath.js has been loaded, or by adding "extensions/verb.js"
|
|
* to the loadFiles array in the easy/load.js file.
