Creating upload button and progress bars using jQuery-File-Upload plugin
<p>I'm trying to use the <a href="http://blueimp.github.com/jQuery-File-Upload/" rel="nofollow">jQuery File Upload</a> plugin to upload some files in an ajax form.  I'm trying to follow the directions for the <a href="https://github.com/blueimp/jQuery-File-Upload/wiki/Basic-plugin" rel="nofollow">"Basic" plugin</a>, but the documentation is a bit sparse.</p>

<p>I don't see any way to create a "Start Upload" button.  I also don't quite understand how to set progress bars for individual uploads.  I see I can set <code>data.context</code> in the <code>add</code> callback, but how does that work if there are multiple files in <code>data.files</code>?</p>
