% This file, apalike.sty, is in the public domain.
% (Last updated 22may09 by Karl Berry.)
% It is a simple style file intended for use with apalike.bst.
% 
% This version has two changes from the original:
% 1) use \refname and \bibname instead of hardwiring
%    the strings "References" and "Bibliography"; this change was first
%    made in the apalike.sty in the germbib package.
% 2) do not define \bibhang if it is already defined.
