% 

% The author thanks to Yacine Daddi Addoun who gave the author the
% motivation to write the style for his bilingual document.  He also thanks
% to the following people;
% 

% Robin Fairbairns who kindly invited the style to CTAN after the author's
% lazy six years failing to upload the style;
% 

% Joseph
% G.\ Rosenstein and Dieter K\"ohler who suggested the author adding the
% function of unbalanced column width incorporated in version 1.1;
% 

% Joaqu\'in Blas who motivated the author to challenge page-wise footnotes;
% 

% Olivier Vogel who pointed out the compatibility problem with coloring
% packages;
% 

% Heiner Richter who asked for the possibility of swapping unbalanced
% columns, revealed two bugs in version 1.22 related to coloring and
% float pages, showed the necessity of \!\coloredwordhyphenated!, and finally
% found the necessity of \!\globalcounter!|*|;
% 

% an anonymous user who reported a very rare-case but severe bug in the
% version~1.1 by which a page can be lost (whoops!);
% 

% Olivier Gerard who found another terrible bug fixed in version 1.21 but
% hidden in \textsf{paracol} for two years by which a column disappears or
% moves to a wrong page (another whoops!\@), suggested to implement
% \!\setcolumnwidth!, \!\marginparthreshold! and \!\thecolumn!  introduced
% in version 1.3, and kindly proofread this manual;
% 

% George Kamel who let the author know the coloring function newborn in
% version 1.2 had a bug fixed in version 1.22 to which he also made a great
% contribution testing many tentative versions with his own colored
% documents;
% 

% another anonymous user who pointed out version 1.22 had yet another
% coloring bug fixed in version 1.24;
% 

% Jean Druel who motivated the author to implement an advanced functionality
% parallel-paging;
% 

% Tilo Arens and other patient users who had wished \Paracol{} would have the
% capability of rule drawing in the gaps separating columns and painting
% backgrounds of columns and so on;
% 

% Michael Bolin who gave the author motivated examples showing the
% necessity of \!\ensurevspace!.
% 

% Tigran Aivazian who reported a memory leak problem fixed in version 1.32;
% 

% Marcus Zelezny and Touhami Mamouni who found an incompatibility with
% \LaTeX{} itself (2015/01/10 or later) and enlighten the author on the cause
% of the problem;
% 

% Manuel Kuehner who reported a bug in text coloring which had hidden
% for five years until the version 1.34 was released;
% 

% ZongXian Wang who found that the paracol misbehaves when an environment
% starts with an unusually tall item;
% 

% and Frank Mittelbach who pointed out bugs in \cs{marginpar} implementation
% and vertical spacing with \cs{trivlist}-like environments, and suggested
% new functionality with \cs{marginnote}, \cs{belowfootnoteskip} and
% \cs{definecolumnpreamble}.
% 
% For the implementation of the style file, the author referred to the base
% implementations of \cs{output} and othe many macros of \LaTeXe{} written
% by Leslie Lamport, Johannes Braams and other authors.  The author also
% referred to \textsf{color} written by David Carlisle and
% \textsf{marginnote} written by Markus Kohm to make the package working
% well with them.
