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.
