       applefile - Radmind AppleSingle file

       To  provide  support for	Mac OS X, radmind is aware of the Mac OS meta-
       data used on HFS+-formatted drives. When	lcreate	uploads	a file denoted
       in  the	transcript as an applefile (type 'a'), it encodes the file and
       the file's metadata to the server as an AppleSingle file. The AppleSin-
       gle  file  is an	archive	containing a file's relevant metadata and data
       in a single file	stream.	The radmind AppleSingle	file has the following

       1)  The AppleSingle header, consisting of a 4-byte magic	number,	4-byte
       version number, 16-byte filler, 2-byte number denoting  the  number  of
       entries in the archive, and 3 header entries, each describing the items
       in the archive and containing a 4-byte entry  id,  4-byte  offset,  and
       4-byte length;

       2)  The	file's	Finder information (32 bytes), which stores the	file's
       Type and	Creator	codes, as well its position in the Finder window;

       3) The file's Resource Fork, which contains things like images, sounds,
       and other data not easily or appropriately stored in the	Data Fork;

       4)  The	file's Data Fork, the portion visible from the Finder, and the
       only part which is considered valid by flat file	systems.

       The radmind tool	lapply similarly decodes the applefile from the	server
       and  restores it	to the client Mac OS X machine running on an HFS+-for-
       matted drive.

       The   Apple   Computer's	   AppleSingle	  RFC	 is    available    at

       ktcheck(1),  lapply(1),	lcreate(1),  lcksum(1),	 lfdiff(1), lmerge(1),
       lsort(1), radmind(8), twhich(1).
