// This is a clone of Ben Nolan's fine behaviour.js for prototype.
// The documentation for behaviour.js at http://bennolan.com/behaviour/
// applies directly to this library.  It *should* be a fully drop-in
// replacement of Ben Nolan's behaviour.js if you have the right version
// of prototype.js.

// If there are any situations where something works in Ben's behaviour.js
// and not (or not as expected) in this, please let me know.

/* the following is not true, yet... it was, but then I realized I was
    using the Selector class wrong */
// I've also enhanced the Behaviour.apply() function to take a base element
// to start from.  prototype's Selector class has this, so it was a trivial
// addition.  Enjoy!
