%% This style attempts to faithfully reproduce the EPTCS bibliography
%% style described at http://biblio.eptcs.org/ . Some deviations occur
%% where biblatex allows for additional information whose presentation
%% is not specified by the above style, e.g., eprint fields containing
%% references to arXiv papers or pagetotals for papers with EIDs. This
%% style includes some of this extra data in a manner that is (hopefully)
%% visually consistent with the preexisting BibTeX style. Individual
%% changes are documented below.
