What regular expression does jQuery use to validate their email?

Question

JQuery can check email addresses:
http://docs.jquery.com/Plugins/Validation

What regular expression (if any) does jQuery use to validate their email?
I would like to do something similar except using javascript regex.

Thanks!

update:

Why am I asking?
I use it for the pattern attribute of my <input> elements.

I ended up using this:

 ^\ S+@ (([a-zA-Z0-9]([a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?\.)+[a-zA-Z]{2,6})$

He uses this regular expression, borrowed from Scott Gonzalez ...

 /^((([az]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([az]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([az]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([az]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([az]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([az]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([az]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([az]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([az]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([az]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))$/i

There is no difference between the regular expression used in the jQuery plugin than regular JavaScript regular expression.
