-/**
- * Create a new remote server that will listen for order on the given port.
- * <p>
- * The available commands are given as arrays of objects (first item is the key,
- * second is the command, the rest are the arguments).
- * <p>
- * The md5 is always a String (the MD5 hash of the access key), the commands are
- * also Strings; the parameters vary depending upon the command.
- * <ul>
- * <li>[md5] PING: will return PONG if the key is accepted</li>
- * <li>[md5] GET_METADATA *: will return the metadata of all the stories in the
- * library (array)</li>
- * *
- * <li>[md5] GET_METADATA [luid]: will return the metadata of the story of LUID
- * luid</li>
- * <li>[md5] GET_STORY [luid]: will return the given story if it exists (or NULL
- * if not)</li>
- * <li>[md5] SAVE_STORY [luid]: save the story (that must be sent just after the
- * command) with the given LUID, then return the LUID</li>
- * <li>[md5] IMPORT [url]: save the story found at the given URL, then return
- * the LUID</li>
- * <li>[md5] DELETE_STORY [luid]: delete the story of LUID luid</li>
- * <li>[md5] GET_COVER [luid]: return the cover of the story</li>
- * <li>[md5] GET_CUSTOM_SOURCE_COVER [source]: return the cover for this source</li>
- * <li>[md5] SET_SOURCE_COVER [source], [luid]: set the default cover for the
- * given source to the cover of the story denoted by luid</li>
- * <li>[md5] CHANGE_SOURCE [luid] [new source]: change the source of the story
- * of LUID luid</li>
- * <li>[md5] EXIT: stop the server</li>
