Hello,

  I've updated the Slide Show (S9) gem [1]. What's new?

  I've added support for light-weight plugins that you can install the
same way as template packs. Example:

  slideshow install analytics

    or

 slideshow install
https://raw.github.com/slideshow-s9/analytics/master/analytics.txt.plugin

  This will install the analytics helper plugin [2]. Now you can use
it in your slides:

   {{ google_analytics code=UA-YOUR-CODE-HERE }}

   To create your own plugins add a manifest to your repo (e.g.
analytics.txt.plugin) that lists your Ruby scripts (e.g.
analytics_helper.rb).

  That's it. Enjoy. Cheers.
