	- linux command: h2xs -A -X -n MARC

0.61  Tue Sep  7 12:56:23 CDT 1999
	- convert version 0.6 into CPAN format (lots of little changes)

0.62  Fri Sep 10 05:18:00 1999
	- revised datastructure to hash of tags plus non-tag elements
	  like 'array' which serve as structured views into data

0.63  Sun Sep 12 20:38:00 1999
	- permit incremental processing to reduce memory footprint

0.65  Fri Sep 17 08:07:42 1999
	- add openmarc,nextmarc,closemarc,deletemarc

0.7   Sun Sep 21 07:15:00 1999
	- major upgrade: revise new for incremental reads and tag maps
	- add selectmarc,searchmarc, createrecord, _joinfield, addfield
	- add error processing and use Carp
	- add header/body/footer outputs
	- revise documentation

0.71  Wed Sep 22 15:50:31 1999
	- compute @tags once in _marc2html, fix $outputall detection
	- add Win32 test and install
	- t/test1.t uses new output file spec, tests append & $var

0.72  Fri Sep 24 07:42:00 1999
	- add getvalue
	- add doc example: xml_header, xml_body, xml_footer
	- add doc example: createrecord, addfield

0.80  Sun Oct  3 17:14:00 1999
	- add isbd and unimarc

0.81  Mon Oct  4 22:25:17 CDT 1999
	- update CPAN doc files: Changes, README, Makefile.PL
	- add isbd to t/test1.t

0.82  Wed Oct  6 13:30:22 CDT 1999
	- Win32 Makefile.PL improvements including automatic html install
	- Added single quotes to hash keys in MARC.pm and t/test1.t to
	  eliminate nuisance warnings from Perl 5.004.

0.83  Mon Oct 11 22:22:00 EST 1999
	- Updated MARC.pm line 108 to store scalar references instead of
	  scalars. This will hopefully cut down on duplication of data in
	  the MARC object.
	- Also, updated the getvalue(), searchmarc() and addfield() methods to 
	  reflect the change in the way subfield data is stored.
	- Added line 220 to return '0 but true' instead of 0 when no records
	  were read in. This will allow for statements like
	  $x->openmarc("test.mrc") || die;

0.84  Tue Oct 12 22:07:18 CDT 1999
	- more Win32 Makefile.PL tweaks after TPJ technical review
	- add binmode for marc file read/write
	- unspecified 'increment' defaults to 0
	- fix repeated subfield in field bug in addfield

0.85  Wed Oct 13 21:19:00 EST 1999
	- modified addfield to push scalar references instead of scalars when 
	  adding subfield data to the $x->[record]{field}{subfield} data member
	  on line 859.
	- updated closemarc to return 1, to allow constructs like
	  $x->closemarc() || die;

0.9   Sun Oct 17 19:48:00 EST 1999
	- modified deletemarc() to support deleting specified fields and
	  subfields
	- modified addfield() to support adding fields in tag order

0.91  Tue Oct 19 18:01:43 CDT 1999

	- add internal subroutines supporting those methods:
		_unpack_ldr,	_bib_format,	_unpack_008,

	- extensive changes to getvalue to cover '000' tag and indicators
	- use getvalue in unpack_008
	- return undef instead of die in _unpack_008
	- allow lineterm option in output, 'format' defaults to 'marc',
	  lineterm to '\n' except MARCMaker (CRLF)
	- add nolinebreak option for MARCBreaker output
	- 'html_header' outputs "Content-type...", 'html_start' does "<body>"
	- _writemarc also updates '000' size data in structure

	- Removed FF_ prefix from @LDR_FIELDS. Left package globals for
          fixed fields and leaders as globals: this should facilitate
	  anybody who wants to subclass for MFHL, community, records.
	- Added pack_008 and pack_ldr. Added get_hash_008 and
	  get_hash_ldr for future tied interface. Fixed bugs. 
	  (FF_ prefixes in hash keys.)

        - created MARC::XML subclass to handle MARC<->XML conversions

0.991  Sun Nov 21 18:49:00 EST 1999 <Summers>
        - removed MARC::XML specific pod from MARC.pm and added to MARC::XML

1.00   Mon Nov 22 22:22:32 CST 1999 <Birthisel>

	- return undef for output failure, test in place of XML

1.01   Sun Dec 05 23:14:15 CST 1999 <Birthisel>
	- add invalid size checks to _readmarc()
	- add header check to _readmarcmaker()

	- added getmatch and insertpos to support update or insert
	   of subfields.
	- added getfields/updatefields for fine-grained access to
	   the {array} structures. Allows "in-place" update of fields.
	- changed add_fields to use add_map. Let's subclasses have a
	   policy of how they want their indices to look.
	- changed _readmarc and _readmarcmaker to use add_map. Good
	   for testing.
	- Added simple tests for *first and *map* series as test4.t
	   More complex and complete tests are in MARC::Tie.
	- Added docs for *map*, getmatch,*fields*,getmatch and insertpos.

1.03   Mon Jan 17 15:21:54 CST 2000 <Birthisel>
