%% Edit by Nelson H. F. Beebe <beebe@sunrise>

[16-Sep-1996]	0.10
		Modify print_item() to add a secondary sort key made
		from the volume number, so that identical labels in a
		periodical bibliography (e.g. from a regular column)
		sort in publication order.

[17-Jan-1996]	0.09
		Add support and documentation for -byday switch.

[29-Oct-1994]	0.08
		Change sort key for -byvolume sorting to include
		year, so that entries that are missing volume numbers
		but have a year will be sorted with other entries from
		the same year.  

		In function value(), change two patterns so that empty
		values of the form "" and {} are recognized properly.
		The old patterns incorrectly expected at least one
		character between the delimiters, which in the case of
		empty strings caused the next line to be included in
		the value string.  This in turn resulted in generation
		of a sort key with a line break, and after removal of
		the sort key, a partial sort key was left in the
		output stream.

[25-Sep-1994]	0.07
		Change sort key for -byvolume sorting to include
		beginning and ending page numbers as separate key
		fields, so that two entries with pages 31--31 and
		31--32 are correctly sorted.  Such instances actually
		occur in the journal Computing Surveys, where two or
		more letters to the editor can start on the same page.

[21-Sep-1994]	0.06
		In function squeeze(), multiple blanks preceding an
		open brace inside value strings were incorrectly
		eliminated.  Rewrite squeeze() to be more careful.

		In function collect_braced_item(), add check for
		meeting an apparent new entry before brace balance is
		achieved, and exit with an error code if this happens.

[??-???-1994]	0.05
		Changes not recorded.

[20-Jul-1994]	0.04
		Add support for recognition of booktitle, so that
		cross-referenced books can be sorted into the
		@Proceedings{...}  section as well.

[15-Jul-1994]	0.03
		Extend -byyear sorting to extract year from citation
		key of the form Jones:1992:ABC (BibNet Project style).

[09-Jun-1994]	0.02
		Add substantial additional commentary, and add support
		for sorting @Proceedings{...} entries in a separate
		section at the end, to conform to BibTeX's
		cross-referencing order requirements.

[17-May-1994]	0.01
		Add support for -byyear switch.

[13-Oct-1992]	0.00
		Initial working version.
