** Let's start with the library base. There's not too much in it...

		rsset	34	;standard lib base
dc_seglist	rs.l	1	;segment list of library (private)
dc_entries	rs.w	1	;number of recognized crunchers
dc_sizeof	=	__RS

** Ok, now let's come to the CrunchInfo structure. There are definitely
** more definitions here...

		rsreset
ci_data		rs.l	1	;pointer to crunched file
ci_name		rs.l	1	;pointer to name (null terminated)
ci_decdata	rs.l	1	;pointer to decrunched file (READ ONLY)
ci_declen	rs.l	1	;length of decrunched file (READ ONLY)
ci_reallen	rs.l	1	;allocated buffer length (READ ONLY)
ci_packnum	rs.b	1	;packer number (READ ONLY)
ci_packtype	rs.b	1	;packer type (READ ONLY)
ci_datalen	rs.l	1	;length of crunched file (for PP data files)
ci_error	rs.w	1	;error code if decrunch failed
ci_extrainfo	rs.l	1	;special info (private)
ci_sizeof	=	__RS

** Packer numbers as defined in this release. These values will stay
** the same in future updates. You might use them to define others than
** the default packer names. See default names after the numbers.
