+ * 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
+ * the port to contact it on
