+\begin{paracol}{2}[\section{Introduction}]
+This document describes the usage of yet another multi-column package named
+\textsf{paracol}.  The unique feature of the package is that columns are
+typeset {\em in parallel.}
+
+Suppose you are writing a bilingual document whose left column is written in
+a language, say English, and right column has the translation of the left
+column in another language, e.g. Japanese.  With the \textsf{paracol}
+package you may write an English part of arbitrary length and then {\em
+switch} to its Japanese counterpart to place both parts side by side.  Of
+course you may return to the English writing similarly.
+
+The column switching is always allowed when you complete an outermost level
+paragraph.  You may be unaware whether a column is broken into multiple
+pages before switching because the package automatically goes back and
+forward to the correct page and vertical position when you switch the
+column.  Moreover, you may {\em synchronize} columns so that the tops of
+the first paragraphs after switching in all columns are vertically aligned.
+At a synchronization point, you may give a single-column text, for example
+a common section header, optionally.  You may also switch single-column and
+multi-column in a page arbitrary.
+
+This manual itself is an example of two-column documents typeset by
+\textsf{paracol}.  Since the author is not familiar with languages other
+than English and Japanese and the latter should be hardly understood by
+most of readers, the right column is the translation of the left English
+column into a computational language.  That is, the right column is the
+\LaTeX{} source code of the left column\footnote{Not really but its essence
+is shown.}.

+familiar with languages other than English
+and Japanese and the latter should be
+hardly understood by most of readers, the
+right column is the translation of the left

+\switchcolumn*[\section{Basic Usage}]
+Loading the package is very simple.  What you have to do is
+\|\usepackage{paracol}| in the preamble.  Note that \textsf{paracol} can be
+used with \LaTeXe{} and does not work with \LaTeX{} 2.09.

+\textit{source}
+
+\switchcolumn*
+The fundamental means of parallel-column typesetting are the environment
+\|paracol| and the command \|\switchcolumn|.  The \|paracol| environment
+needs an argument to specify the number of columns.  Thus the following is
+the basic construct for two-parallel-column documents.
+\begin{quote}
+\|\begin{paracol}{2}|\\
+\textit{left column text}\\
+\|\switchcolumn|\\
+\textit{right column text}\\
+\|\switchcolumn|\\
+\textit{left column text}\\
+\|\switchcolumn|\\
+\textit{right column text}\\
+\|\switchcolumn|\\
+\mbox{\hspace{4em}}$\vdots$\\
+\|\end{paracol}|
+\end{quote}
+
+\switchcolumn
+\begin{Verbatim}

+The fundamental means of parallel-column
+typesetting are the environment \|paracol|
+and the command \|\switchcolumn|.  ...

+\switchcolumn[0]
+The \|\switchcolumn| command may have an
+optional argument to specify the column
+number (zero origin) to start.  ...
+\end{Verbatim}
+
+\switchcolumn[0]
+The \|\switchcolumn| command may have an optional argument to specify the
+column number (zero origin) to start.  That is, \|\switchcolumn[0]| means to
+switch to the leftmost column, \|\switchcolumn[1]| is to start the second
+column and so on.  Thus the \|\switchcolumn| without the optional argument
+may be considered as \|\switchcolumn[|$i+1\bmod{n}$\|]| where $i$ is the
+last column number and $n$ is the number of columns given to \|paracol|
+environment.
+
+
+
+\switchcolumn[0]*[\section{Column Synchronization}\label{sec:sync}]
+The \|\switchcolumn| command may also be followed by a `\|*|' to {\em
+synchronize} columns.  After you switch from a column to another by
+\|\switchcolumn*| (or \|\switchcolumn[|$i$\|]*|), all the columns are
+vertically aligned at the bottom of the {\em deepest} one preceding the
+command.  For example, the previous section has three \|\switchcolumn*|
+commands at which left and right columns are vertically aligned.
+
+The {\em starred} version of \|\switchcolumn| may have an optional argument
+to specify a multi-column text whose bottom is the vertical alignment
+points of the columns.  For example, \|\section| commands in this manual are
+given as optional arguments of\break\|\switchcolumn*| like;
+\begin{Verbatim}
+  \switchcolumn*[\section{Basic Usage}]
+\end{Verbatim}
+The \|paracol| environment may also start with a multi-column text by
+specifying it as the optional argument of \|\begin{paracol}|.  For example,
+at the beginning of this document, the author put;
+\begin{Verbatim}
+  \begin{paracol}[\section{Introduction}]
+\end{Verbatim}
+
+\switchcolumn
+\begin{Verbatim}
+\switchcolumn[0]*[%

+\|\switchcolumn| may have an optional

+whose bottom is the vertical alignment

+\begin{column*}[\section{Environments for Columns}\label{sec:env}]
+\subsection{Environment \texttt{column}}
+The \|\switchcolumn| is simple but you may prefer to pack the contents of a
+column in an environment.  The \|column| environment is available for this
+well-structurization of \LaTeX{} sources for parallel columned documents. A
+construct;
+\begin{quote}
+\|\begin{column}|\\
+\textit{text for a column}\\
+\|\end{column}|
+\end{quote}
+is (almost) equivalent to;
+\begin{quote}
+\|\switchcolumn|\\
+\textit{text for a column}
+\end{quote}
+The \|column*| environment is also available for the column synchronization
+and may have an optional argument for multi-column text.

+  \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 \|figure*| and
+\|table*| environments as usual.  A single-column figure\slash table will be
+placed in the column in which you put \|figure| and \|table|.  For example,
+the contents of \|figure| environment in a \|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 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 synchronize columns.
+The rule is as follows; after you synchronize columns in a page, the page
+cannot have top-floats any more.  When you synchronize columns,
+\textsf{paracol} fixes a virtual horizontal line in the page as the
+synchronization 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 \|figure| environments for the figures shown
+in the previous page into the \|leftcolumn*| and \|rigtcolumn| environment
+for the previous section.
+
+\subsection{Footnotes and Marginal Notes}
+Footnotes are also put at the bottom of the column in which \|\footnote|
+commands and their references (like this\footnote{%
+%
+An example of footnote.})
+%
+reside, as shown in page~2 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 just right of the column.  Thus marginal notes
+of non-leftmost and non-rightmost columns will appear in the space
+separating columns rather than the margin of a page.}.
+
+\subsection{Local and Global Counters}
+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, sub-section numbering is local and the headings in right
+columns have typewriter-face numbers.
+
+This happens because the author declared the counters \|figure| and \|table|
+are \emph{global} in the preamble of this document by saying;
+\begin{itemize}\item[]%{
+\|\globalcounter{figure}|\\
+\|\globalcounter{table}|
+\end{itemize}%}
+and do nothing about \|footnote| and \|subsection| counters.  By default,
+all the counters except for \|page| are local to columns.  The value of a
+local counter of a column is saved somewhere when you leave the column, and
+it is restored when you revisit the column.  The initial value of the
+local counters are the value they have at \|\begin{paracol}|.  After you
+close the \|paracol| environment, the values of the left-most column are
+used for the rest of your document.
+
+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| or commands such as
+\|\caption| and \|\section|.  Note that the value of a global counter
+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
+\|table| environment here to increment \|table| counter, the right-column
+table at the bottom of page~\pageref{tab:right} would be Table~3 because its
+\|table| environment does not appear yet in the source code.
+
+Another counter which the author made global in this documnet is
+\|section|.  As explained in Section~\ref{sec:sync}, an optional
+multi-column text of column switching is considered as in the left-most
+column.  Since \|\section| commands in this document are always multi-column
+texts, so far, it seems unnecessary to make \|section| global because it is
+incremented correctly in the left-most column.  However, the stepping
+\|section| has a side effect to reset its decendent counter \|subsection|
+and referred from \|\thesubsection| command.  Thus if \|section| were local,
+the right-column sub-sections in Section~\ref{sec:env} would be numbered as
+``0.1'', ``0.2'' and ``0.3'' because the local value of \|section| would be
+zero.  Moreover, the right-column sub-sections of this section would be
+``0.4'', ``0.5'' and ``0.6'' because stepping \|section| local to
+left-columns would not reset \|subsection| local to right-columns.
+
+You may give a local appearance to a counter \textit{ctr} for the $i$-th
+column (zero origin) by a command;
+\begin{itemize}\item[]%
+ \|\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
+\|\thesubsetion| for right columns.
+%
+\begin{Verbatim}
+  \definethecounter{footnote}{1}{%
+    \textit{\arabic{footnote}}}
+  \definethecounter{subsection}{1}{%
+    \texttt{%
+      \arabic{section}.\arabic{subsection}}}

+\section{Closing \texttt{paracol} Environment and Page Flushing}
+The final example shown here is this single-column text which the author put
+after \|paracol| environment is closed.  As you are seeing, \|paracol|
+environment can be finished at any vertical position in a page and can be
+followed by ordinary single column texts.
+
+\begin{paracol}{2}
+\begin{leftcolumn}
+The environment may also be restarted anywhere you like as shown here.
+
+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 affects the layout of the right column.
+
+To flush all columns in a page, a command \|\flush|\AB\|page| is available.
+This command in $i$-th column is almost equivalent to;
+\begin{itemize}\item[]%{
+\|\switchcolumn[|$i$\|]*[\newpage]|
+\end{itemize}%}
+but more robust\footnote{%
+%
+For example \texttt{\string\switchcolumn*} may flush a page for the
+synchronization and thus \texttt{\string\newpage} may leave an empty page.}.
+%
+The ordinary page breaking command \|\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.
