For the +% ``witched'' version of all these, we had chosen to typeset them in the +% relative script style associated to the style of the affected subformula. +% For example, in a construct like +% \begin{verbatim}$W_{\overrightwitchonbroom{x_{1}+\dots+x_{n}}}$\end{verbatim} +% the subformula "x_{1}+\dots+x_{n}", argument of the +% "\overrightwitchonbroom" command, is set in script style, therefore the +% style applied to the covering broom (and witch) will be the scriptscript +% style. We already remarked in Subsection~\ref{ssS:StandardArrows} that +% this is not what the standard ``over\mbox{-}\slash under-arrow'' commands +% do: instead, they use for the arrow the same style as that in which the +% argument gets typeset. The reason for this different behavior was that, +% with the same style of the affected subformula, the witch would have looked +% too large; but when the witch isn't there, both solutions are viable, and +% we do provide both. +% +% ^^A \paragraph{Brooms\slash pitchforks in the same relative style.} +% We have, in the first place, a set of commands for placing brooms or +% pitchforks (a.k.a.\ version-0.01-styled brooms) over or under a subformula, +% setting them in the same style as the subformula itself. +% \DescribeMacro{\overrightbroom} +% \DescribeMacro{\overleftbroom} +% \DescribeMacro{\underrightbroom} +% \DescribeMacro{\underleftbroom} +% There are four ``over\mbox{-}\slash under-arrow-like'' extensible +% brooms\ldots +% \begin{flushleft} +% "\overrightbroom "\marg{subformula} \\ +% "\overleftbroom "\marg{subformula} \\ +% "\underrightbroom"\marg{subformula} \\ +% "\underleftbroom "\marg{subformula} +% \end{flushleft} +% \DescribeMacro{\overrightpitchfork} +% \DescribeMacro{\overleftpitchfork} +% \DescribeMacro{\underrightpitchfork} +% \DescribeMacro{\underleftpitchfork} +% \ldots and four corresponding ``over\mbox{-}\slash under-arrow-like'' +% extensible pitchforks: +% \begin{flushleft} +% "\overrightpitchfork "\marg{subformula} \\ +% "\overleftpitchfork "\marg{subformula} \\ +% "\underrightpitchfork"\marg{subformula} \\ +% "\underleftpitchfork "\marg{subformula} +% \end{flushleft} +% +% ^^A \paragraph{Brooms\slash pitchforks in relative script style.} +% Then, for each of the commands just listed, a corresponding variant is +% provided that sets the broom, or the pitchfork, in the relative script +% style of the style applied to \meta{subformula}, and which is named +% following the same convention we already used for the commands of +% Subsection~\ref{ssS:StandardArrows}, that is, inserting the "script" +% substring. +% \DescribeMacro{\overscriptrightbroom} +% \DescribeMacro{\overscriptleftbroom} +% \DescribeMacro{\underscriptrightbroom} +% \DescribeMacro{\underscriptleftbroom} +% Thus, again, we find four ``over\mbox{-}\slash under-arrow-like'' +% extensible brooms\ldots +% \begin{flushleft} +% "\overscriptrightbroom "\marg{subformula} \\ +% "\overscriptleftbroom "\marg{subformula} \\ +% "\underscriptrightbroom"\marg{subformula} \\ +% "\underscriptleftbroom "\marg{subformula} +% \end{flushleft} +% \DescribeMacro{\overscriptrightpitchfork} +% \DescribeMacro{\overscriptleftpitchfork} +% \DescribeMacro{\underscriptrightpitchfork} +% \DescribeMacro{\underscriptleftpitchfork} +% \ldots and four matching ``over\mbox{-}\slash under-arrow-like'' extensible +% pitchforks: +% \begin{flushleft} +% "\overscriptrightpitchfork "\marg{subformula} \\ +% "\overscriptleftpitchfork "\marg{subformula} \\ +% "\underscriptrightpitchfork"\marg{subformula} \\ +% "\underscriptleftpitchfork "\marg{subformula} +% \end{flushleft} +% +% \paragraph*{Please note:} +% Since all of the commands listed in this subsection omit the witch, none +% of them has got a \mbox{$*$-form} for adding a cat (the cat can only go +% with the witch: no witch, no cat). +% +% \subsubsection{Summary of the naming scheme} +% +% It is worth noting that the commands for the extensible brooms\slash +% pitchforks follow a consistent naming scheme: the name is of the form +% \begin{center} +% \texttt{\bslash}\meta{x-over-under}\meta{opt-script}^^A +% \meta{left-right}\meta{opt-witch}\meta{broom-pitchf} +% \end{center} +% where +% \begin{flalign*} +% \meta{x-over-under} &\longrightarrow +% \texttt{x}\binvert\texttt{over}\binvert\texttt{under} & +% \meta{opt-script} &\longrightarrow +% \meta{empty}\binvert\texttt{script} \\ +% \meta{left-right} &\longrightarrow +% \texttt{left}\binvert\texttt{right} & +% \meta{opt-witch} &\longrightarrow +% \meta{empty}\binvert\texttt{witchon} \\ +% \meta{broom-pitchf} &\longrightarrow +% \texttt{broom}\binvert\texttt{pitchfork} +% \end{flalign*} +% with the constraint that \meta{opt-script} must be \meta{empty} if either \( \meta{x-over-under} = +% \texttt{x} \) or \( \meta{opt-witch} \neq \meta{empty} \). +% +% \section +% [Installing the pacakge code and documentation] +% {Installing the package code and documentation\footnote{^^A +% Recall that you need to read this section only in the unusual case that you +% have to carry out a manual installation from the sources;
