+/**
+ * WordPress Filesystem Class for implementing SSH2.
+ *
+ * To use this class you must follow these steps for PHP 5.2.6+
+ *
+ * @contrib http://kevin.vanzonneveld.net/techblog/article/make_ssh_connections_with_php/ - Installation Notes
+ *
+ * Complie libssh2 (Note: Only 0.14 is officaly working with PHP 5.2.6+ right now, But many users have found the latest versions work)
+ *
+ * cd /usr/src
+ * wget http://surfnet.dl.sourceforge.net/sourceforge/libssh2/libssh2-0.14.tar.gz
+ * tar -zxvf libssh2-0.14.tar.gz
+ * cd libssh2-0.14/
+ * ./configure
+ * make all install
+ *
+ * Note: Do not leave the directory yet!
+ *
+ * Enter: pecl install -f ssh2
+ *
+ * Copy the ssh.so file it creates to your PHP Module Directory.
+ * Open up your PHP.INI file and look for where extensions are placed.
+ * Add in your PHP.ini file: extension=ssh2.so
+ *
+ * Restart Apache!
+ * Check phpinfo() streams to confirm that: ssh2.shell, ssh2.exec, ssh2.tunnel, ssh2.scp, ssh2.sftp  exist.
+ *
+ * Note: as of WordPress 2.8, This utilises the PHP5+ function 'stream_get_contents'
+ *
+ * @since 2.7
+ * @package WordPress
+ * @subpackage Filesystem
+ * @uses WP_Filesystem_Base Extends class
