% EG:	bibliographies style for EUROGRAPHICS publications
%    derived from BI_NUM (which originates from ACM Transactions bibliography style)
%            and  ALPHA  (with \etalchar{*}).
%
%    modifications:
%            - labels for bibitem are computed according to alpha.bst
%            - names are included in {\sc ... :}
%            - no period after line listing the authors
%            - no comma within a name
%            - names are separated by comma
%            - new database item STANDARD; its like MANUAL but an optional
%              VERSION field is added after TITLE
%
%    History
%     7.08.90 (DF) above modifications
%    20.11.90 (DF) add title handling for GARTICLE: format.german.title
%    24.05.91 (DF) port to BibTeX 0.99 (using ACM.BST as the source to start from)
%    10.04.93 (DF) fix semicolon between editors and "(Ed[s].)": scapify;
%                   use \uppercase{longest.label} to reserve enough space
%    11.09.03 (DF) adapt to LateX 2e conventions
%     9.01.06 (DF) Fixing double ',' after second editor in format.innames
%                   contributed by Dmitry Sokolov
%
%
% 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.
