% Greek.sty
% A latex style file for use with Silvio Levy's classical Greek fonts
% (see TUGboat 9.1 (1988), pp. 20 ff.). The following style file
% consists of Levy's own greekmac.tex macros unaltered, followed by
% some macros published by R. Wonneberger and slightly modified
% by D. Wujastyk, which fix a problem in using Greek accents in LaTeX
% footnotes. See below for more explanation of the footnote stuff.
%
% Usage: \documentstyle[greek]{book} ... as normal. This makes all the
% greekmac macros available, and fixes the footnote problem.

% The following macros are taken from Reinhard Wonnenberger's
% article "Chapter Mottos ..." in TUGboat 7(3), 1986, p.179. I (Dominik
% Wujastyk) have edited out those bits in which Reinhard was altering
% the default values of LaTeX to his own liking. If you want to do
% that as well, you might prefer to do it in a separate style file.
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% The following macros avoid the need to read the footnote text as
% a parameter. They are taken from PLAIN.TEX.
% LaTeX control sequences have been substituted for those from
% PLAIN, and are marked thus: %LATEX

% \newinsert\footins
% \def\footnote#1{\let\@sf\empty % parameter #2 (the text) is read later

% Format the footnote label inside the footnote; based on book.sty:
