+%\title{Wick contractions in \LaTeX\ with |simplewick.sty|}
+%\author{Jind\v rich Koloren\v c}
+%\date{2006/10/29}
+%\maketitle
+%
+%\noindent
+%This is a manual accompanying the style file |simplewick.sty|
+%providing macros |\acontraction| and |\bcontraction| to draw Wick
+%contractions above and below expressions, respectively. The
+%functionality is best illustrated by an example,
+%$$
+%\contraction{}{a}{{}^{\dagger}_i(t_1)a^{\dagger}_j(t_1)}{a}
+%\relax%
+%\contraction[2ex]{a^{\dagger}_i(t_1)}{a}{%
+%{}^{\dagger}_j(t_1)a_j(t_1)a_i(t_1)%
+%a^{\dagger}_i(t_2)a^{\dagger}_j(t_2)a_j(t_2)}{a}
+%\relax%
+%\contraction[3ex]{a^{\dagger}_i(t_1)%
+%a^{\dagger}_j(t_1)a_j(t_1)}{a}{{}_i(t_1)%
+%a^{\dagger}_i(t_2)}{a}
+%\relax%
+%\bcontraction{a^{\dagger}_i(t_1)%
+%a^{\dagger}_j(t_1)a_j(t_1)a_i(t_1)}%
+%{a}{{}^{\dagger}_i(t_2)a^{\dagger}_j(t_2)}{a}
+%\relax%
+%a^{\dagger}_i(t_1)a^{\dagger}_j(t_1)a_j(t_1)a_i(t_1)
+%a^{\dagger}_i(t_2)a^{\dagger}_j(t_2)a_j(t_2)a_i(t_2)\,.
+%$$
+%
+%\section{Usage}
+%The syntax will be explained on something simpler, however. The
+%sequence
+%\begin{verbatim}
+%$$
+%\contraction{}{A}{B}{C}
+%\contraction[2ex]{A}{B}{C}{D}
+%ABCD
+%$$
+%\end{verbatim}
+%renders as
+%$$
+%\contraction{}{A}{B}{C}
+%\contraction[2ex]{A}{B}{C}{D}
+%ABCD\,.
+%$$
+%The parameters of the macro |\contraction[]{}{}{}{}| (which is a
+%synonym for |\acontraction[]{}{}{}{}|) are as follows.
+%\newbox\listlabelbox
+%\begin{list}{$\triangleright$}{
+%  \setlength{\topsep}{.6em}
+%  \setlength{\itemsep}{.5ex}
+%  \setlength{\parsep}{0pt}
+%  \setbox\listlabelbox=\hbox{$\triangleright$}
+%  \setlength{\labelwidth}{\wd\listlabelbox}
+%  \setlength{\leftmargin}{1.5\parindent}
+%}
+%\item The first (optional) argument is the height of the
+%contraction. When omitted (as in the first contraction above) it
+%defaults to 1ex,
+%\item the second argument contains the expression that lies before the
+%contraction start,
+%\item the third argument contains the expression, above which the
+%start of the contraction is centered,
+%\item the fourth argument is the
+%part of the formula that is bridged by the contraction, and finally
+%\item the contraction ends above the center of the last argument of
+%the macro.
+%\end{list}
+%Note that the macro itself typesets only the contraction alone and rewinds
+%back to allow for multiple contractions. Therefore, the expression to
+%appear below the contraction(s) has to be repeated once more when you
+%are finished with contractions themselves.
+%
+%I guess now it is the right time to move to that ``real life'' example
+%from the beginning of this manual. Its source is
+%\begin{verbatim}
+%$$
+%\contraction{}{a}{{}^{\dagger}_i(t_1)a^{\dagger}_j(t_1)}{a}
+%%
+%\contraction[2ex]{a^{\dagger}_i(t_1)}{a}{%
+%{}^{\dagger}_j(t_1)a_j(t_1)a_i(t_1)%
+%a^{\dagger}_i(t_2)a^{\dagger}_j(t_2)a_j(t_2)}{a}
+%%
+%\contraction[3ex]{a^{\dagger}_i(t_1)%
+%a^{\dagger}_j(t_1)a_j(t_1)}{a}{{}_i(t_1)%
+%a^{\dagger}_i(t_2)}{a}
+%%
+%\bcontraction{a^{\dagger}_i(t_1)%
+%a^{\dagger}_j(t_1)a_j(t_1)a_i(t_1)}%
+%{a}{{}^{\dagger}_i(t_2)a^{\dagger}_j(t_2)}{a}
+%%
+%a^{\dagger}_i(t_1)a^{\dagger}_j(t_1)a_j(t_1)a_i(t_1)
+%a^{\dagger}_i(t_2)a^{\dagger}_j(t_2)a_j(t_2)a_i(t_2)\,.
+%$$
+%\end{verbatim}
+%
+%
+%\section{Contractions inside the text --- stretching and shrinking}
+%The macro |\contraction| is prone to giving not entirely satisfactory
+%results when the formula is under stress or tension, i.e., when \TeX\
+%shrinks or stretches ``the glue'' from its natural width. When we try
+%to squeeze the line
+%\begin{verbatim}
+%Contraction under stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$
+%and with no stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$.
+%\end{verbatim}
+%into a narrow box, we get
+%\vskip 1em
+%\noindent
+%\hbox to \textwidth{\hfil%
+%\framed{%
+%\vbox{\hsize=23.75em
+%\noindent
+%Contraction under stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$
+%and with no stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$.
+%}}\hfil}
+%\vskip 1em
+%\noindent
+%This is not quite right since the contraction drawn on the first line
+%is slightly too long, although its length is precisely the same as
+%the length of the contraction on the second line --- they were entered
+%via the same piece of code, after all. The style
+%|simplewick.sty| offers a fix for this inconsistency in the form of
+%the macro |\nomathglue{}| that prevents \TeX\ to shrink or stretch its
+%argument. When used
+%\begin{verbatim}
+%Contraction under stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \nomathglue{%
+%     \bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)}
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$
+%and with no stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$.
+%\end{verbatim}
+%the outcome should look precisely as we wanted.
+%\vskip 1em
+%\noindent
+%\hbox to \textwidth{\hfil%
+%\framed{%
+%\vbox{\hsize=23.75em
+%\noindent
+%Contraction under stress
+%$
+%\contraction{}{\bar G}{{}_1(\mathbf{q}_1)\>\>{}}{\bar G}
+%  \nomathglue{\bar G_1(\mathbf{q}_1)\>\>{}\bar G_2(\mathbf{q}_2)}
+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)

+%=\bar\chi_{12}(\mathbf{q}_1-\mathbf{q}_2)
+%$.
+%}}\hfil}
+%
+%
+%\section{Alternatives}
+%An alternative method for typesetting Wick contractions with \LaTeX\ is a
+%|wick.sty| by Taichiro Kugo, available at
+%\begin{verbatim}
+%http://www2.yukawa.kyoto-u.ac.jp/~kugo/index-e.html
+%\end{verbatim}
+%It is actually a more advanced solution than the one presented
+%here (which is the reason why I call this package
+%|simplewick|). Unfortunately, |wick.sty| seems to be somewhat
+%conflicting with |amsmath| package. For example, I did not succeed to
+%draw the |wick.sty| contractions above accented characters (such as
+%those in the stretching examples above) when |amsmath| was
+%loaded. Without |amsmath| it was just fine, however.
+%
+%
+%\section{Credits}
+%The package |simplewick.sty| is based on the code from |thophys.sty|
+%by Thorsten Ohl that dates back to 1994. I only added the contractions
+%below expressions (|\bcontraction|), the stretching/shrinking fix
+%|\nomathglue| and this documentation. Contact information can be
+%obtained by issuing a command |\simplewickcontact|.
