%% This is an unofficial Latex class for Authors of AIRCC Papers.
%% It tries to follow the formating guidelines set in the official
%% template "aircc_template.doc" as close as possible.
%% Unfortunately, some are not easily applicable in Latex. Examples include
%% text style combinations like bold italicized small caps which simply are
%% generally not supported. Some font sizes are also not directly supported.
