%% This bibliography style file is intended for texts in ENGLISH.
%% This is an author-year citation style bibliography. This style file is
%%  based on    natbib.sty   package by Patrick W. Daly.
%% The form of the \bibitem entries is
%%   \bibitem[Jones et al.(1990)]{key}...
%%   \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
%% The essential feature is that the label (the part in brackets) consists
%% of the author names, as they should appear in the citation, with the year
%% in parentheses following. There must be no space before the opening
%% parenthesis!
%% 
%% The \cite command functions as follows (\cite is equal to \citep command):
%%   \citep{key}              =>   (Jones et al., 1990)
%%   \citep*{key}             =>   (Jones, Baker, and Smith, 1990)
%%   \citep[chap. 2]{key}     =>   (Jones et al., 1990, chap. 2)
%%   \citep[e.g.][]{key}      =>   (e.g. Jones et al., 1990)
%%   \citep[e.g.][p. 32]{key} =>   (e.g. Jones et al., 1990, p. 32)
%%   \citet{key}              =>   Jones et al. (1990)
%%   \citet*{key}             =>   Jones, Baker, and Smith (1990)
%%   \citeauthor{key}         =>   Jones et al.
%%   \citeauthor*{key}        =>   Jones, Baker, and Smith
%%   \citeyear{key}           =>   1990
