New description:

 - level is a symbol or #f, indicating lower than the lowest level

   (message-levels [levels]) -> level

     - parameter that gets/sets the active message levels

     - levels is a list of symbol defining the legal set of levels
     and the order of precedence. () means no levels

   (message-level [level]) -> level

     - parameter that gets/sets the active message level

     - the active message level determines whether a message
     is processed any further. any message with a level lower
     than the current level is ignored.

   (message level msg . args)

     - msg is a string, and args are objects

     - a level of #f will never be seen unless () = (message-levels)

   (warning msg . args) & (##sys#notice msg . args)

     - wrappers around `message'
