(function($) {
  '$:nomunge'; // Used by YUI compressor.
  
  // Method: jQuery.fn.equalizeBottoms
  // 
  // Equalize the bottoms of all selected elements.
  // 
  // Usage:
  // 
  // > jQuery('selector').equalizeBottoms( [ bottom ] );
  // 
  // Arguments:
  // 
  //  bottom - (Number) An optional bottom y position to force selected element
  //    bottoms to. If omitted, bottom is computed automatically by measuring
  //    height of all selected elements and choosing the bottom-most bottom. You
  //    will probably never, ever use this.
  // 
  // Returns:
  // 
  //  (jQuery) The initial jQuery collection of elements.
