+% \section{Introduction}
+% ^^A --------------------------------------------------
+%
+% A persistent problem with the |\marginpar| command is that the
+% marginalia produced often show up on the wrong margin. This has
+% been noted in the \LaTeX\ bugs database.^^A
+% \footnote{See \url{http://www.Uni-Mainz.DE/cgi-bin/ltxbugs2html}:
+% \href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=latex/2361}{latex/2361},
+% \href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=latex/2484}{latex/2484},
+% \href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=latex/2617}{latex/2617}.}
+%
+%
+% The problem occurs most likely when a marginpar appears near
+% the top of a page. The problem is exacerbated when
+% the page break penalties are adjusted so that the page look is
+% quite ragged. In cases like this, if there is a deal of white
+% space on a page, the marginpars on the next page will be on the
+% wrong side for the same length of the page.
+% The reason for this is that the \LaTeX\ output routine is not
+% in complete synchronization with the \TeX\ page breaker, so that
+% sometimes
+% material might still move to a later page \emph{after} \LaTeX's
+% marginpar algorithm has determined a page number for the marginpar.
+%
+% The fix suggested in the bugs database is to insert |\pagebreak|
+% commands at the places where the page breaks naturally fall;
+% then the marginpars will appear on the correct side. However, this is
+% awkward and unpleasant work for a document that changes
+% regularly, and seems to fly against the spirit of \LaTeX.
+%
+% A different approach was suggested by D. E. Knuth in his
+% \emph{Macros for Jill}\footnote{Originally published in TUGboat
+% \textbf{8}, pp.~309--314, reprinted in his \emph{Digital
+% Typography} pp.~185--193.}: make two |.dvi| files, one with all
+% notes in the left margin, the other one with all notes in the
+% right margin. Then print the odd pages from one file, and the
+% even pages from the other file; merge them by hand.
+%
+% However, Knuth also mentions the possibility to use an auxiliar
+% file to save the page information for each marginpar and use this
+% information to position it correctly in a second \TeX\ run; and
+% this is the strategy adopted by \PackageName.
+% Each marginpar is assigned a unique number; the output routine
+% writes the number of the last marginpar of each page\slash column
+% to the |.aux| file, and this information is used in
+% |\@addmarginpar| to position the current marginpar on the correct
+% margin.
+%
+%
+% ^^A --------------------------------------------------
+% \section{Usage}
+% ^^A --------------------------------------------------
+% Just insert |\usepackage{mparhack}| into your document preamble.
+% After the first run, you'll probably get the warning message
+% `\texttt{Marginpars may have changed. Rerun to get them right}'.
+% This is similar to \LaTeX's warning `\texttt{Label(s) may have
+% changed}'; it indicates that the |.aux| file doesn't contain the
+% information needed to position the marginpars correctly, due to
+% some changes in the document since the last run. The warning
+% should go away after running \LaTeX\ again (eventually several
+% times if there's also a table of contents etc.).
+%
+% \DescribeMacro{debug}^^A
+% If you think something is going wrong, the package also has a
+% \texttt{debug} option; this will output a lot of tracing
+% information and will add numbers to the marginpars in the |.dvi|
+% file for reference.
+%
+%
+% ^^A --------------------------------------------------
+% \section{Bugs\slash Restrictions}
+% ^^A --------------------------------------------------
+% \begin{itemize}
+% \item
+% The package works with the |twocolumn| document option, but not
+% with the |multicol| package (you can't use marginpars inside
+% the |multicols| environment).
+% \item
+% The package uses one command sequence per page, and the total number
+% of command sequences available is limited on most \TeX\ systems.
+% Note however that most current \TeX\ implementations
+% can allocate more than several thousand command names, and some can
+% be configured to allocate more than the default during run-time,
+% so this shouldn't be a problem for moderately sized documents.
+% \item
+% The package has to hook into three commands of the \LaTeX2e\ output
+% routine (by redefining some command), so it requires at least
+% \LaTeX\ version 1997/04/14 and might break with future \LaTeX\
+% versions that change these commands.
+% We try to detect this by requiring a version newer than 1997/04/14
+% and using some heuristics to check if the redefinitions have worked.
+% You should watch out for this warning message:\par
+% {\ttfamily\footnotesize\begin{tabular}{@{}l@{}l@{}}
+%LaTeX Warning:&\ You have requested release `1997/04/14' of LaTeX,\\
+% &\ but only release `...' is available.
+% \end{tabular}}\par\noindent
+% It might be that the package also works with older versions of \LaTeX,
+% but this hasn't been tested. If one of the heuristics detects an incompatible
+% change, it will raise an error:\par
+% {\ttfamily\footnotesize\begin{tabular}{@{}l@{}}
+%Package mparhack Error: Couldn't hook into command `xyz'.
+% \end{tabular}}\par\noindent
+% \vskip-\lastskip\noindent
+% It might also happen that the heuristics don't detect a change
+% properly. If the package simply seems to fail, this could be a reason.
+% In both cases, please send a bug report to
+% \href{mailto:stefanulrich@users.sourceforge.net}{\texttt{stefanulrich@users.sourceforge.net}}
+% (if neccessary including the
+% |.log| file of your \LaTeX\ run with the \texttt{debug}
+% package option enabled). Suggestions/improvements are also welcome,
+% of course.
+% \end{itemize}

+% \section{Implementation}
+% ^^A --------------------------------------------------
+%
+% ^^A --------------------------------------------------
+% \subsection{Overview}\label{implementation}
+% ^^A --------------------------------------------------
+% Here's the algorithm for recording the positioning information for
+% marginpars in more detail: Every marginpar has a unique number $n$ and
+% writes to the |.aux| file a string like\par\medskip
+% ^^A
+% \begin{tabular}{@{}l}
+% |\def\mph@nr{|$n$|}|.
+% \end{tabular}\par\medskip
+%
+% The commands shipping out the columns and pages write to the
+% |.aux| file strings like:\par\medskip
+% ^^A
+% \begin{tabular}{@{}l}
+% |\mph@setcol{|$x{\texttt{:}}$|\thepage}{\mph@nr}|,
+% \end{tabular}\par\medskip\noindent
+% ^^A
+% with $x = \mbox{i}$ for the first column and $x = \mbox{ii}$
+% otherwise. Then when reading the |.aux|
+% file at the begin of the \LaTeX\ run, |\mph@nr| will be substitued
+% by the number of the last marginpar (the value of the |\mph@nr| command
+% read before that),
+% and |\mph@setcol| will assign that number to the command sequence |\csname|
+% |mph@last@|$x{\texttt{:}}$|\thepage\endcsname|; so this will contain
+% the number of the last marginpar on column\slash page $x{\texttt{:}}$|\thepage|.
+%
+% Later on, in the document itself, |\@addmarginpar| will be able to check the value of
+% |\csname| |mph@last@|$x{\texttt{:}}$\Com{thepage}\Com{end\-csname},
+% using the current values for $x$ and |\thepage|. Then there are two
+% cases:
+%
+% (a) |\csname| |mph@last@|$x{\texttt{:}}$|\thepage\endcsname| is
+% undefined, which means that there has been no |.aux| file
+% previously, or that there are more pages\slash marginpars than in
+% the previous run; in this case, |\@addmarginpar| will fall back to using
+% the value of |\c@page| to determine the current page number (yielding the
+% same result as without this package), or
+%
+% (b) |\csname| |mph@last@|$x{\texttt{:}}$|\thepage\endcsname| is defined as
+% an integer $z$, the number of the last marginpar on |\thepage|.
+% Then $z \leq n$, the number of the current marginpar.^^A
+% \footnote{$z$ cannot be greater than $n$: this would
+% mean that \TeX\ had shifted some material (including a marginpar)
+% from later pages to earlier pages, which AFAIK cannot happen.}
+% While $z < n$, the page counter will be incremented (inside a group)
+% until |\csname| |mph@last@|$x{\texttt{:}}$|\thepage\endcsname| for
+% that new page is $\geq n$, or until
+% we end up in case (a). The incremented value for the page counter
+% now represents the actual page number of the current marginpar,
+% and it will be used instead of the original page counter in the
+% check for even-\slash oddness.
+%
+% ^^A --------------------------------------------------
+% \subsection{Code}
+% ^^A --------------------------------------------------
+%
+% We need at least \LaTeX\ version 1997/04/14 which introduced
+% |\normalsfcodes| into |\@outputdblcol|.

+% ^^A --------------------------------------------------
+% \subsubsection{Booleans, Options, etc.}
+% ^^A --------------------------------------------------
+% Some boolean switches which we will be using:
+% |\if@mph@firstcol@| indicates that the current column is the
+% first column, |\if@mph@warning@| toggles the warning message
+% about changed marginpars, and |\if@debug@| toggles printing (lots
+% of) debugging messages.

+ \ifx#1\@empty\else
+ \typeout{DBG (#1): #2}%
+ \fi
+ \fi
+}
+% \end{macrocode}
+% \end{macro}
+% The |debug| package option sets |@debug@| to true and adds
+% numbers to each marginpar by redefining \Com{@xmpar} and
+% \Com{@ympar}. The numbers are put into boxes of dimension
+% zero so that they don't alter the spacing.

+% ^^A --------------------------------------------------
+% \subsubsection{Patching the output routine}
+% ^^A --------------------------------------------------
+% We have to hook into 3 commands that are part of \LaTeX's output routine:
+% |\@addmarginpar|, |\@outputdblcol| and |\@outputpage|. For the latter, we can use the default
+% \LaTeX\ mechanism |\g@addto@macro|. For the others, this is more difficult,
+% since the changes need to go somewhere `in between'.
+%
+% One could use hard redefinitions (plus
+% \Com{CheckCommand*} to verify that the correct version of
+% the command was being defined); but this soon gets too bothersome
+% with new \LaTeX2e\ versions introducing minor changes that don't
+% affect the stuff which we are concerned, but that nevertheless
+% would require multiplying the redefinitions for the various versions.
+%
+% So instead, we locally redefine some
+% commands to hook into the existing definitions. As a heuristic of
+% detecting whether we change the appropriate commands, we check
+% the values of some special counters \Com{mph@chk@xyz} that get
+% incremented by some of the `hooks'.
+%
+% \changes{v1.3a}{2003/05/22}{%
+% Use \Com{g@addto@macro} for \Com{@outputpage} to
+% improve compatibility with e.g. the memoir class
+% }%
+% \changes{v1.2}{2000/02/29}{%
+% Added \Com{CheckCommand*} for \Com{@addmarginpar}, \Com{@outputpage}
+% and \Com{@outputdblcol}
+% }%
+% \changes{v1.2b}{2000/09/01}{%
+% Replaced \Com{CheckCommand*} and the full redefinitions of
+% \Com{@addmarginpar}, \Com{@outputpage} and \Com{@outputdblcol}
+% by hooking into certain commands inside them
+% }%
+%
+% \begin{macro}{\mph@error}
+% Error message if something suspicious happened with the redefintions:
+% \begin{macrocode}
+\newcommand\mph@error[1]{%
+ \PackageError{mparhack}{%
+ Couldn't hook into command `#1'
+ }{%
+ This means that a LaTeX version incompatible with
+ mparhack.sty^^J%
+ has been used. See also the section on `Bugs/Restrictions'^^J%
+ in mparhack.dvi. Please send an email about this bug to^^J%
+ <stefanulrich@users.sourceforge.net>, along with the file `\jobname.log'.
+ }%
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@addmarginpar}
+% This command adds the marginpar box to the current page.
+% We change the \Com{c@page} counter and the \Com{if@firstcolumn} switch
+% to the values that have been set correctly by the \Com{mph@get@margin}
+% command. There's no further error checking done here.
+%
+% \begin{macrocode}
+\newcommand\mph@orig@c@page{}
+\newcommand\mph@orig@addmarginpar{}
+\let\mph@orig@addmarginpar\@addmarginpar

+ \fi
+ \mph@orig@addmarginpar
+ \c@page=\mph@orig@c@page
+}
+
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@outputpage}
+% Add the |\mph@outputpage@hook| hook to |\@outputpage|.
+% We need to decrement |\c@page|, since |\@outputpage| will
+% have incremented it after dumping the page contents.
+% The group in |\mph@outputpage@hook| is to keep this change local.
+% \begin{macrocode}
+\newcommand*\mph@outputpage@hook{%
+ \bgroup
+ \advance\c@page\m@ne
+ \immediate\write\@auxout{%

+ }%
+ \egroup
+}
+\g@addto@macro{\@outputpage}{\mph@outputpage@hook}
+
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\@outputdblcol}
+% In case an entire twocolumn page is finished, this command calls
+% \Com{hb@xt@} with the boxes for the two columns inside, and each
+% one needs to set a marker with the current column number. So
+% we hook into \Com{hb@xt@} and check if its first argument equals
+% \Com{columnwidth} (\Com{hb@xt@} is also called for the entire page,
+% but in this case the first argument is \Com{textwidth}).
+%
+% The current column number is represented by \Com{mph@chk@dcl}, and at
+% the end we check if this number equals 0 (in which case the
+% page hadn't been fininshed yet, and we didn't need to do anything)
+% or 2 (the `interesting' case); else we signal an error.
+%
+% \begin{macrocode}
+\newcommand\mph@orig@hb@xt@{}
