// init_ui.js
// 2011-01-19

// This is the web browser companion to fulljslint.js. It is an ADsafe
// lib file that implements a web ui by adding behavior to the widget's
// html tags.

// It stores a function in lib.init_ui. Calling that function will
// start up the JSLint widget ui.

// option = {adsafe: true, fragment: false}
