-/**
- * Slinky allows you to go back and forth between "long" and shortened URLs
- * using popular URL shortening services.
- *
- * Slinky assumes you have cURL installed and working, and requires the JSON
- * extension installed if you're working with a service that uses JSON.
- *
- * Slinky will ONLY work with PHP5+
- *
- * It supports some of the more popular services, with easy extensibility for
- * adding your own relatively easily. It defaults to using TinyURL
- * for shortening URLs. If you want to use some of the other services, you need
- * to set some configuration options before actually shortening/lengthening
- * URLs. I'd strongly suggest that you cache results using memcached, a local
- * DB or whatever to avoid having to hit APIs etc every time you encounter a
- * URL.
- *
- * Slinky supports shortening, and auto-detection (for lengthening URLs)
- * using these services:
- * - Bit.ly
- * - Tr.im
- * - TinyURL
- * - Is.Gd
- * - Fon.gs
- * - Micurl.com
- * - ur1.ca
- * - Ptiturl
- * - Tighturl
- * - 2tu.us
- * - Snipr / Snipurl / Snurl.com / Sn.im
- *
- *
- * To use Slinky:
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * - Creates a new Slinky instance, will default to using TinyURL for ->short();
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au', new Slinky_Bitly() );
- * - Creates new Slinky, forces use of Bit.ly for ->short();
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * echo $slinky->short();
- * - echos the short version of http://dentedreality.com.au/ (default to TinyURL)
- *
- * $slinky = new Slinky( 'http://tinyurl.com/jw5sh' );
- * echo $slinky->long();
- * - echos out the long version of http://tinyurl.com/jw5sh (which should be http://dentedreality.com.au/)
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * echo $slinky->long();
- * - Attempts to lengthen the URL, but will not auto-detect which service it is
- * so it will just output the original URL. Useful for always attempting to
- * lengthen any URL you come across (fails gracefully)
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * $slinky->set_cascade( array( new Slinky_Trim(), new Slinky_IsGd(), new Slinky_TinyURL() ) );
- * echo $slinky->short();
- * - Uses the powerful cascade mode to make sure that we get a short URL from
- * Tr.im, Is.Gd or TinyURL (in that order).
- *
- * See specific service class definitions below for examples of how to use them,
- * as some services allow (or require) additional properties before you can use
- * them (for authentication etc).
- *
- * To use a different service with Slinky, just create your own class and
- * extend Slinky_Service(). Make sure you implement url_is_short(), url_is_long(),
- * make_short() and make_long(). If you need to GET or POST a URL, you can use
- * ->url_get() and ->url_post(), which your class will have inherited.

-/**
- * Slinky allows you to go back and forth between "long" and shortened URLs
- * using popular URL shortening services.
- *
- * Slinky assumes you have cURL installed and working, and requires the JSON
- * extension installed if you're working with a service that uses JSON.
- *
- * Slinky will ONLY work with PHP5+
- *
- * It supports some of the more popular services, with easy extensibility for
- * adding your own relatively easily. It defaults to using TinyURL
- * for shortening URLs. If you want to use some of the other services, you need
- * to set some configuration options before actually shortening/lengthening
- * URLs. I'd strongly suggest that you cache results using memcached, a local
- * DB or whatever to avoid having to hit APIs etc every time you encounter a
- * URL.
- *
- * Slinky supports shortening, and auto-detection (for lengthening URLs)
- * using these services:
- * - Bit.ly
- * - Tr.im
- * - TinyURL
- * - Is.Gd
- * - Fon.gs
- * - Micurl.com
- * - ur1.ca
- * - Ptiturl
- * - Tighturl
- * - 2tu.us
- * - Snipr / Snipurl / Snurl.com / Sn.im
- *
- *
- * To use Slinky:
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * - Creates a new Slinky instance, will default to using TinyURL for ->short();
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au', new Slinky_Bitly() );
- * - Creates new Slinky, forces use of Bit.ly for ->short();
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * echo $slinky->short();
- * - echos the short version of http://dentedreality.com.au/ (default to TinyURL)
- *
- * $slinky = new Slinky( 'http://tinyurl.com/jw5sh' );
- * echo $slinky->long();
- * - echos out the long version of http://tinyurl.com/jw5sh (which should be http://dentedreality.com.au/)
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * echo $slinky->long();
- * - Attempts to lengthen the URL, but will not auto-detect which service it is
- * so it will just output the original URL. Useful for always attempting to
- * lengthen any URL you come across (fails gracefully)
- *
- * $slinky = new Slinky( 'http://dentedreality.com.au/' );
- * $slinky->set_cascade( array( new Slinky_Trim(), new Slinky_IsGd(), new Slinky_TinyURL() ) );
- * echo $slinky->short();
- * - Uses the powerful cascade mode to make sure that we get a short URL from
- * Tr.im, Is.Gd or TinyURL (in that order).
- *
- * See specific service class definitions below for examples of how to use them,
- * as some services allow (or require) additional properties before you can use
- * them (for authentication etc).
- *
- * To use a different service with Slinky, just create your own class and
- * extend Slinky_Service(). Make sure you implement url_is_short(), url_is_long(),
- * make_short() and make_long(). If you need to GET or POST a URL, you can use
- * ->url_get() and ->url_post(), which your class will have inherited.

+/**
+ * Slinky allows you to go back and forth between "long" and shortened URLs
+ * using popular URL shortening services.
+ *
+ * Slinky assumes you have cURL installed and working, and requires the JSON
+ * extension installed if you're working with a service that uses JSON.
+ *
+ * Slinky will ONLY work with PHP5+
+ *
+ * It supports some of the more popular services, with easy extensibility for
+ * adding your own relatively easily. It defaults to using TinyURL
+ * for shortening URLs. If you want to use some of the other services, you need
+ * to set some configuration options before actually shortening/lengthening
+ * URLs. I'd strongly suggest that you cache results using memcached, a local
+ * DB or whatever to avoid having to hit APIs etc every time you encounter a
+ * URL.
+ *
+ * Slinky supports shortening, and auto-detection (for lengthening URLs)
+ * using these services:
+ * - Bit.ly
+ * - Tr.im
+ * - TinyURL
+ * - Is.Gd
+ * - Fon.gs
+ * - Micurl.com
+ * - ur1.ca
+ * - Ptiturl
+ * - Tighturl
+ * - 2tu.us
+ * - Snipr / Snipurl / Snurl.com / Sn.im
+ *
+ *
+ * To use Slinky:
+ *
+ * $slinky = new Slinky( 'http://dentedreality.com.au/' );
+ * - Creates a new Slinky instance, will default to using TinyURL for ->short();
+ *
+ * $slinky = new Slinky( 'http://dentedreality.com.au', new Slinky_Bitly() );
+ * - Creates new Slinky, forces use of Bit.ly for ->short();
+ *
+ * $slinky = new Slinky( 'http://dentedreality.com.au/' );
+ * echo $slinky->short();
+ * - echos the short version of http://dentedreality.com.au/ (default to TinyURL)
+ *
+ * $slinky = new Slinky( 'http://tinyurl.com/jw5sh' );
+ * echo $slinky->long();
+ * - echos out the long version of http://tinyurl.com/jw5sh (which should be http://dentedreality.com.au/)
+ *
+ * $slinky = new Slinky( 'http://dentedreality.com.au/' );
+ * echo $slinky->long();
+ * - Attempts to lengthen the URL, but will not auto-detect which service it is
+ * so it will just output the original URL. Useful for always attempting to
+ * lengthen any URL you come across (fails gracefully)
+ *
+ * $slinky = new Slinky( 'http://dentedreality.com.au/' );
+ * $slinky->set_cascade( array( new Slinky_Trim(), new Slinky_IsGd(), new Slinky_TinyURL() ) );
+ * echo $slinky->short();
+ * - Uses the powerful cascade mode to make sure that we get a short URL from
+ * Tr.im, Is.Gd or TinyURL (in that order).
+ *
+ * See specific service class definitions below for examples of how to use them,
+ * as some services allow (or require) additional properties before you can use
+ * them (for authentication etc).
+ *
+ * To use a different service with Slinky, just create your own class and
+ * extend Slinky_Service(). Make sure you implement url_is_short(), url_is_long(),
+ * make_short() and make_long(). If you need to GET or POST a URL, you can use
+ * ->url_get() and ->url_post(), which your class will have inherited.
