- * Create a new remote server that will listen for order on the given port.

- * The key is always a String, the commands are also Strings; the parameters
- * vary depending upon the command.
- * <ul>
- * <li>[key] GET_METADATA *: will return the metadata of all the stories in the
- * library</li>
- * <li>[key] GET_STORY [luid]: will return the given story if it exists (or NULL

- * <li>[key] SAVE_STORY [luid]: save the story (that must be sent just after the
- * command) with the given LUID</li>
- * <li>[key] DELETE_STORY [luid]: delete the story of LUID luid</li>
