JsRun.java

/**
 * A trivial bootstrap class that simply adds the path to the
 * .js file as an argument to the Rhino call. This little hack
 * allows the code in the .js file to have access to it's own 
 * path via the Rhino arguments object. This is necessary to 
 * allow the .js code to find resource files in a location 
 * relative to itself.
 *
 * USAGE: java -jar jsrun.jar path/to/file.js
