-* The constructor ASS() also takes in a parser object. This is created by XHR'ing ass.pegjs and using PEG.js to process it. It is also possible to use the PEG.js API server-side to create the parser as a JS file. You can then serve the pre-generated parser along with libjass.js and the rest of your site's JavaScript. Instructions for generating the parser outside the browser (using node.js) are on the PEG.js website linked above.
