%STARTSECTION{"summary"}%
The jQuery Cycle Plugin is a lightweight slideshow plugin. Its implementation
is based on the JQueryInnerFade Plugin by Torsten Baldes, the Slideshow Plugin by
Matt Oakes, and the jqShuffle Plugin by Benjamin Sterling. It supports
pause-on-hover, auto-stop, auto-fit, before/after callbacks, click triggers and
many transition effects. It also supports, but does not require, the Metadata
Plugin and the Easing Plugin.

---++ Usage

Add the ==jqCycle== class to the container holding the elements to be cycled. 

---++ Commands
The cycle function can be passed a command string in the form:

<verbatim class="js">
$('#slideshow').cycle('command');
</verbatim>

The following command strings are supported:

<verbatim class="js">
'pause'   // pauses the slideshow, slideshow can be resumed with 'resume' command 
'resume'  // resumes a paused slideshow 
'toggle'  // toggles the pause/resume state of the slideshow 
'next'    // advances slideshow to next slide 
'prev'    // advances slideshow to previous slide 
'stop'    // stops the slideshow 
'destroy' // stops the slideshow and unbinds all events 
</verbatim>

---++ Options
The following default options are provided by the plugin. They can be overridden by passing an options object to the cycle method, by using metadata on the container element, or by redefining these values in your own code. Lots of cool effects can be achieved by taking advantage of these options, but none of them are required. So override the ones you like and ignore the ones you don't care about.

<verbatim class="js">
// override these globally if you like (they are all optional) 
$.fn.cycle.defaults = { 
        activePagerClass: 'activeSlide', // class name used for the active pager link
        after:             null,  // transition callback (scope set to element that was shown):  function(currSlideElement, nextSlideElement, options, forwardFlag)
        allowPagerClickBubble: false, // allows or prevents click event on pager anchors from bubbling
        animIn:            null,  // properties that define how the slide animates in
        animOut:           null,  // properties that define how the slide animates out
        aspect:            false,  // preserve aspect ratio during fit resizing, cropping if necessary (must be used with fit option)

        autostopCount:     0,         // number of transitions (optionally used with autostop to define X)
        backwards:         false, // true to start slideshow at last slide and move backwards through the stack

        timeout:           4000,  // milliseconds between slide transitions (0 to disable auto advance)
