  3:  * This plugin implements <i>tiny URLs</i> such as used by the tweet_news plugin
  4:  *
  5:  * <i>Tiny URLs</i> are short unique to Zenphoto. They are short digital strings that
  6:  * allow Zenphoto to locate the object referenced. They are prefixed by <var>tiny/<var>
  7:  * if <i>mod_rewrite</i> is active otherwise they have the form <var>index.php?p=ddddd&t</var> .
  8:  *
  9:  * These can be useful if you want to minimize the length of URLs or if you want to
 10:  * obscure the information that they might convey.
