% Update to have a sorting order by year, by authors.

% ACM Transactions bibliography style (24-Jan-88 version)
%    A lot like abbrv.bst, but names come out "Last, initials", and in \sc.
%    Some dates are parenthesized.
%
%    History
%     2/ 6/86	(HWT)	Original version, by Howard Trickey.
%     3/ 5/86	(HWT)	Put in pp. everywhere but articles, as per ACM style.
%     1/24/88	(OP&HWT) Updated for BibTeX version 0.99a, Oren Patashnik;
%			corrected the abbreviations to "Mar." and "Sept.";
%			THIS `acm' VERSION DOES NOT WORK WITH BIBTEX 0.98i.
%     07/09/13	(SG) Adapted for PHD thesis.
