DESCRIPTION
    This property holds the description of readable details on an object.
    The indices of the mapping are the detail-ids, the value for each
    index is the read message of the detail.
    The read details are addressed in commands as "<detailid> on <objectid>"
    resp. "<detailid> of <objectid>".
    The read description may be a string or a closure evaluating to
    a string.

    To set resp. remove details, the two lfuns AddSubReadMsg() and
    RemoveSubReadMsg() should be used.
      void AddSubReadMsg(string det, string desc)
	Add a read-detail <det> with the message <desc>.
	<det> may be an array of detail ids, which then all get the
	same message text.

      void RemoveSubReadMsg(string det)
	Remove the read detail <det>.
	<det> may be an array of detail ids, which then all get removed.

    The detail is queried via the Read() lfun, which calls the lfun
    GetSubReadMsg(), which returns the message of the given detail
    or 0, if the detail is not defined.

    During an actual look command, the parsed detailid is stored in
    this_player() as the command data entry "<filename_of_object>:subid".
    Read() checks this entry to see if the object's or a detail's
    read message is queried.

EXAMPLE
    AddSubReadMsg("rune", "You utter the word, but nothing happens.\n");
