- * Create a {@link RemoteLibrary} linked to the given server.
- * <p>
- * Note that the key is structured:
- * <tt><b><i>xxx</i></b>(|<b><i>yyy</i></b>|<b>wl</b>)(|<b>rw</b>)</tt>
- * <p>
- * Note that anything before the first pipe (<tt>|</tt>) character is
- * considered to be the encryption key, anything after that character is
- * called the subkey (including the other pipe characters and flags!).
- * <p>
- * This is important because the subkey (including the pipe characters and
- * flags) must be present as-is in the server configuration file to be
- * allowed.
- * <ul>
- * <li><b><i>xxx</i></b>: the encryption key used to communicate with the
- * server</li>
- * <li><b><i>yyy</i></b>: the secondary key</li>
- * <li><b>rw</b>: flag to allow read and write access if it is not the
- * default on this server</li>
- * <li><b>wl</b>: flag to allow access to all the stories (bypassing the
- * whitelist if it exists)</li>
- * </ul>
- * <p>
- * Some examples:
- * <ul>
- * <li><b>my_key</b>: normal connection, will take the default server
- * options</li>
- * <li><b>my_key|agzyzz|wl</b>: will ask to bypass the white list (if it
- * exists)</li>
- * <li><b>my_key|agzyzz|rw</b>: will ask read-write access (if the default
- * is read-only)</li>
- * <li><b>my_key|agzyzz|wl|rw</b>: will ask both read-write access and white
- * list bypass</li>
- * </ul>
- *
- * @param key
- * the key that will allow us to exchange information with the
- * server
- * @param host
- * the host to contact or NULL for localhost
- * @param port
