%% This work consists of the files fifo-stack.dtx, and fifo-stack.ins.
%% 
%% The command:
%%   pdflatex fifo-stack.ins
%% followed by:
%%   pdflatex fifo-stack.dtx
%% will produce the derived files: fifo-stack.sty, fifo-stack-test.tex,
%% and fifo-stack.pdf.
%% 
%% The command:
%%   pdflatex fifo-stack-test.tex
%% will regression test the fifo-stack package. Output will be found in
%% fifo-stack-test.lgout. If pdflatex completes with no errors, then all
%% regression tests passed.
