%%% Double column output routines,
%%% with single and double column insertions,
%%% to be positioned at page or column top, page or column bottom, page
%%% or column center, or full page floating insertion.
%%% This code was originally based on Frank Mittlebach's multicol.sty.
%%% The concept of how to balance columns is due to Donald Knuth. The
%%% way to integrate the changed output routine into the standard LaTeX
%%% output routine is due to Frank.
%%% The method of making the single and double column insertions and the
%%% changes in the output routines to accomodate these features are mine.
