* Provides functionality to dynamically load only the brushes that a needed to render the current page.
|

|
*
|

|
|
* There are two syntaxes that autoload understands. For example:
|
||
|
|
*
|
||
|
|
* SyntaxHighlighter.autoloader(
|
||
|
|
* [ 'applescript', 'Scripts/shBrushAppleScript.js' ],
|
||
|
|
* [ 'actionscript3', 'as3', 'Scripts/shBrushAS3.js' ]
|
||
|
|
* );
|
||
|
|
*
|
||
|
|
* or a more easily comprehendable one:
|
||
|
|
*
|
||
|
|
* SyntaxHighlighter.autoloader(
|
||
|
|
* 'applescript Scripts/shBrushAppleScript.js',
|
||
|

* 'actionscript3 as3 Scripts/shBrushAS3.js'
