% This document describes the usage of yet another multi-column package named

% Suppose you are writing a bilingual document whose left column is written in

% 
% The {\em\Uidx\cswitch} is always allowed when you complete an outermost

% \!\switchcolumn!|*| (or \!\switchcolumn!|[|$i$|]*|), all the columns are
% vertically aligned at the bottom of the {\em deepest} one preceding the

% commands at which left and right columns are vertically aligned.
% 
% The {\em starred} version of \!\switchcolumn! may have an optional

%   \end{tabular}}
% \end{table}
% \subsection{Figures and Tables}
% As shown in this page, double-column figures\slash tables (or those
% spanned multiple columns if you have three or more) may be placed by
% \env{figure*} and \env{table*} environments as usual\footnote{

% 

% See Section~\ref{sec:problem} for the appearance order issue of
% double-column floats.}.
% 

% A single-column figure\slash table will be placed in the column in which
% you put \env{figure} and \env{table}.  For example, the body of a
% \env{figure} environment in a \env{leftcolumn} environment is
% \emph{always} placed in a left column.  That is, even if the column of the
% \emph{current} page does not have enough room to place the figure, it will
% not be thrown to the right column but will be placed in the left column of
% the next page\footnote{

% 

% Or some farther page if \LaTeX{} cannot solve the placement problem wisely.}.
% 
% Another caution about float placement is that you have to be careful when
% you try to put a top-float explicitly with |t|-option or implicitly without
% placement option (i.e., |tbp| in most classes) and to \sync{}e columns.
% The rule is as follows; after you \sync{}e columns in a page, the page
% cannot have top-floats any more.  When you \sync{}e columns,
% \textsf{paracol} fixes a virtual horizontal line in the page as the
% \sync{}ation barrier.  Thus no top-floats cannot be added above the
% line\footnote{

% 

% Even if you have enough space above, sorry.}.
% 

% Therefore, the author put two \env{figure} environments for the figures
% shown in this page into the \env{leftcolumn*} and \env{rightcolumn}
% environment for the previous section.
% 
% \subsection{Footnotes and Marginal Notes}
% \changes{v1.2-2}{2013/05/11}
% 	{Add a footnote mentioning page-wise footnotes.}

%
% Footnotes are also put at the bottom of the column in which \!\footnote!
% commands and their references reside (like this\footnote{

% 

% Unless you specify to make footnotes {\em page-wise} as explained in
% Section \ref{sec:ref-scfnote} and \ref{sec:fnnp}.}),
% 

% as shown in page~\pageref{fn:first} and this page.  Marginal
% notes behave similarly like what you are seeing in the left margin of this
% sentence\marginpar{

% 

% \raggedright An example of marginal note.}
% 

% and the right marginal note in this page\footnote{

% 

% If you have three or more columns, marginal notes of the second or
% succeeding columns are placed in the right margin in default setting.  The
% \textsf{paracol} package solves the placement problem of marginal notes
% from two or more columns sharing a side margin by moving some of them down
% if they conflict over the space with each other.}.
% 
% \subsection{Local and Global Counters}
% \UsageIndex{local counter}
% \UsageIndex{global counter}
% 

% You probably found that the numbering of figures and tables is \emph{global}
% while that of footnotes are \emph{local}.  That is, the figure in the right
% column of the previous page has number~3 following its left-column
% counterpart Figure~2.  The tables in the page are also numbered as 1 and 2
% crossing the column boundary.  However, the footnotes in each column have
% their own numbering sequence.  Moreover, the footnote numbers in left
% columns are typeset in roman font while those in right columns have italic
% shapes.  Similarly, subsection numbering is local and the headings in right
% columns have typewriter-face numbers.
% 
% This happens because the author declared the counters \counter{figure} and
% \counter{table} are \emph{global} in the preamble of this document by
% saying;
% \begin{itemize}\item[]
% \Uidx{\!\globalcounter!}|{figure}|\\
% \!\globalcounter!|{table}|
% \end{itemize}
% and do nothing about \counter{footnote} and \counter{subsection} counters.
% By default, all the counters except for |page| are local to columns.  The
% value of a \lcounter{} of a column is saved somewhere when you leave the
% column, and it is restored when you revisit the column.  The initial values
% of the \lcounter{}s are the values they have at
% \!\begin!|{|\env{paracol}|}|.  After you close the \env{paracol}
% environment, the values of the leftmost column are used for the rest of
% your document until you start new \env{paracol} environment.  On a
% restart, \lcounter{}s in a column have the values they had at the last
% \Endparacol, except for those which have been modified outside the
% environment because the modifications are \emph{broadcasted} to
% \lcounter{}s in all columns.  You will see the effect of this
% inter-environment counter value conservation in the footnote numbers in
% the right column in page~\pageref{fn:right3} and \pageref{fn:right4}.
% 
% This broadcasting of a \lcounter{} value can be done explicitly in
% \env{paracol} environments by a command $\Uidx{\!\synccounter!}\Arg{ctr}$.
% This command makes $\mathit{ctr}$ in all columns have the value of that in
% the column in which the command appears.  In addition, another command
% \Uidx{\!\syncallcounters!} performs this broadcasting for all \lcounter{}s.
% 
% If you make a counter global by the command \!\globalcounter!, the
% save/restore operations are not performed to the counter and thus it is
% globally incremented by |\[ref]|\AB|stepcounter|
% 

% \SpecialIndex{\refstepcounter}\SpecialIndex{\stepcounter}

% 

% or commands such as \!\caption! and \!\section!.  Note that the value of a
% \gcounter{} depends on the place where it is incremented (or set) in
% the \emph{source code} rather than where it appears in the output.  Thus
% if the author put a \env{table} environment here to increment \env{table}
% counter, the right-column table at the bottom of page~\pageref{tab:right}
% would be Table~3 because its \env{table} environment does not appear yet
% in the source code.  Note that, however, though the counter \counter{page}
% is global as expected, its numbering is consistent among all columns as
% far as you refer to the value by $\!\pageref!\Arg{label}$ and/or see the
% values in table of contents, etc.
% 
% Another counter which the author made global in this document is
% \counter{section}.  As explained in Section~\ref{sec:sync}, an optional
% \mctext{} of \cswitch{} is considered as in the leftmost column.  Since
% \!\section! commands in this document are always given in \mctext{}s, so
% far, it seems unnecessary to make \counter{section} global because it is
% incremented correctly in the leftmost column.  However, the stepping
% \counter{section} has a side effect to reset its descendent counter
% \counter{subsection} and referred to from \!\thesubsection! command.  Thus
% if \counter{section} were local, the right-column subsections in
% Section~\ref{sec:env} would be numbered as ``0.1'', ``0.2'' and ``0.3''
% because the local value of \counter{section} would be zero.  Moreover, the
% right-column subsections of this section would be ``0.4'', ``0.5'' and
% ``0.6'' because stepping \counter{section} local to the left column would
% not reset \counter{subsection} local to the right column.
% 
% You may give a local appearance to a counter \textit{ctr} for the $i$-th
% column (zero origin) by a command;
% \begin{itemize}\item[]
% \Uidx{\!\definethecounter!}|{|\textit{ctr}|}{|$i$|}{|\textit{def}|}|
% \end{itemize}
% where \textit{def} is to be the body of the local definition of
% |\the|\textit{ctr}.  For example, the preamble of this document has the
% following to give non-default defitions to \!\thefootnote! and
% \!\thesubsection! for right columns.
% 

%\begin{Verbatim}
%  \definethecounter{footnote}{1}{%

% The last issue is to flush a page.  The ordinary \!\newpage! command works
% as you expect.  If you say \!\newpage! in the left column in a page, the
% contents following it will appear in the left column in the next page.  Note
% that this does not affect the layout of the right column.
% 
% To flush all columns in a page, a command \Uidx{\!\flushpage!} is
% available.  This command in $i$-th column is almost equivalent to;
% \begin{itemize}\item[]
% \!\switchcolumn!|[|$i$|]*[|\!\newpage!|]|
% \end{itemize}
% but more robust\footnotemark\label{fn:flush}.
% The ordinary page breaking command \Uidx{\!\clearpage!} may also be used
% to flush all columns and to start a fresh page, but it has a side effect
% to put all figures and tables which are not yet output.
