jquery resolved this for me with its .append() function - used this to load the complete jquery ui package

/*
 * FILENAME : project.library.js
 * USAGE    : loads any javascript library
 */
    var dirPath = "../js/";
    var library = ["functions.js","swfobject.js","jquery.jeditable.mini.js","jquery-ui-1.8.8.custom.min.js","ui/jquery.ui.core.min.js","ui/jquery.ui.widget.min.js","ui/jquery.ui.position.min.js","ui/jquery.ui.button.min.js","ui/jquery.ui.mouse.min.js","ui/jquery.ui.dialog.min.js","ui/jquery.effects.core.min.js","ui/jquery.effects.blind.min.js","ui/jquery.effects.fade.min.js","ui/jquery.effects.slide.min.js","ui/jquery.effects.transfer.min.js"];

    for(var script in library){
        $('head').append('');
    }

To Use - in the head of your html/php/etc after you import jquery.js you would just include this one file like so to load in the entirety of your library appending it to the head...
