+% 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. Wonnenberger 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.
+% 29 Jan 1991

+% 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
+%   \ifhmode\edef\@sf{\spacefactor\the\spacefactor}\/\fi

+%
+% Format the footnote label inside the footnote; based on book.sty:
+\def\@makefnlabel{\@@par \parindent 1em\noindent
+   \hbox to 1.8em{\hss$^{\@thefnmark}$}}
+%
+% From latex.tex, for comparison:
+% \long\def\@footnotetext#1{\insert\footins{\footnotesize
+%     \interlinepenalty\interfootnotelinepenalty
+%     \splittopskip\footnotesep
+%     \splitmaxdepth \dp\strutbox \floatingpenalty \@MM

+%     {\rule{\z@}{\footnotesep}\ignorespaces
+%       #1\strut}}}
+%
+% Rewritten on the basis of plain.tex:
+\def\fo@t{\ifcat\bgroup\noexpand\next \let\next\f@@t
+  \else\let\next\f@t\fi \next}
+\def\f@@t{\bgroup
+  \rule{\z@}{\footnotesep}\ignorespaces                 %LATEX
+  \aftergroup\@foot\let\next}
+\def\f@t#1{#1\@foot}
+% \def\@foot{\strut\egroup}
+\def\@foot{\strut\egroup                                %LATEX
+  \ifhmode\spacefactor\@x@sf\relax\fi}                  %LATEX
+\def\footstrut{\vbox to\splittopskip{}}
+\skip\footins=\bigskipamount % space added when footnote is present
+\count\footins=1000 % footnote magnification factor (1 to 1)
+\dimen\footins=8in % maximum footnotes per page
