%  This style-option file, apalike-plus.sty, is based on apalike.sty.
%  As such, it can be used to redefine \cite and thebibliography for:
%  - production of do-it-yourself author-date bibliographies
%  - use with BibTeX, with \bibliographystyle{apalike}.
%
%  It differs from apalike.sty in that:
%  - a command \bibtitle is defined, to generate the bibliography title
%  - a command \bibheadtitle is defined, to generate the text to be used
%    by \pagestyle{headings}
%  - \bibtitle and \bibheadtitle are set to generate "References" and
%    "REFERENCES" respectively.
%  - an \addcontentsline{toc}{...}{\bibtitle} command is issued.
%  Thus:
%  - the default bibliography title is "References", but can be changed by
%    having \renewcommand{\bibtitle}{...} before \begin{thebibliography}
%    or \bibliography
%  - the default page header text is "REFERENCES", but can be changed by
%    \renewcommand{\bibheadtitle}{...}
%  - \tableofcontents will give a table of contents that mentions the
%    bibliography.
