+% However, \cs{cap} must be used cautiously in some very particular
+% cases, for the closing brace of its argument may prevent a rule from
+% being applied. To take an example, as seen above
+% \vpageref{ref:muhammaduni}, the transliteration of
+% \arb[fullvoc]{\cap{m}u.hammaduN 'l-nabI} must be
+% \arb[trans]{\cap{m}u.hammaduN 'l-nabI}, as nouns having the
+% \arb[trans]{tanwIn} take a \arb[trans]{kasraT} in pronunciation
+% before \arb[trans]{'alifu 'l-wa.sli}. In this case, encoding
+% \arb[fullvoc]{mu.hammaduN} like so: |\cap{mu.hammaduN}| is wrong,
+% because the closing brace would prevent \package{arabluatex} from
+% detecting the sequence \meta{-uN} immediately followed by
+% \meta{'-l}. Fortunately, this can be circumvented in a
+% straightforward way by inserting only part of the noun in the
+% argument of \cs{cap} vz. up to the first letter that is to be
+% uppercased, like so: |\cap{m}u.hammaduN|.

+% \section{\LaTeX\ Commands in Arabic environments}
+% \label{sec:commands-in-arb}
+% \paragraph{General principle} \LaTeX\ commands are accepted in
+% Arabic environments. The general principle which applies is that
+% single-argument commands (\cs{command}\marg{arg}) such as
+% \cs{emph}\marg{text}, \cs{textbf}\marg{text} and the like, are
+% assumed to have Arabic text as their arguments:---
+% \begin{quote}
+%   |\abjad{45}| |kitAbu-hu| |\emph{fI| |'l-\cap{`AdAti}}|
+%   \arb[voc]{\abjad{45} kitAbu-hu \emph{fI l-\cap{`AdAti}}}
+%   \arb[trans]{45 kitAbu-hu \emph{fI 'l-\cap{`AdAti}}}.\footnote{This
+%   is odd in Arabic script, but using such features as \cs{emph} or
+%   \cs{textbf} is a matter of personal taste.}
 % \end{quote}
 % 
+% The same applies to footnotes:---
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluacode}
+\renewcommand{\footnoterule}%
+   {\hfill\noindent\rule[1mm]{.4\textwidth}{.15mm}}
+\begin{arab}
+'inna 'abI kAna mina 'l-muqAtilaTi\footnote{al-muqAtilaTi:
+al-muqAtilIna.}, wa-kAnat 'ummI min `u.zamA'i buyUti
+'l-zamAzimaTi\footnote{al-zamAzimaTu: .tA'ifaTu mina
+'l-fursi.}.
+\end{arab}
+\end{arabluacode}
+% \iffalse
+%</example>
+% \fi
+%
+% Some commands, however, do not expect running text in their
+% arguments, or one may wish to insert English text eg. in footnotes
+% or in marginal notes. \package{arabluatex} provides a set of
+% commands to handle such cases.
+%
+% \DescribeMacro{LR} \cs{LR}\marg{arg} is designed to typeset its
+% argument from left to right. It may be used in an Arabic
+% environment, either \cs{arb}\marg{Arabic text} or \cs{begin}|{arab}|
+% \meta{Arabic text} \cs{end}|{arab}|, for short insertions of left to
+% right text, or to insert any \LaTeX\ command that would otherwise be
+% rejected by \package{arabluatex}, such as commands the argument of
+% which is expected to be a dimension or a unit of measurement.
+%
+% \DescribeMacro{RL} \cs{RL}\marg{arg} does the same as
+% \cs{LR}\marg{arg}, but typesets its argument from left to right. Even
+% in an Arabic environment, this command may be useful. For example, to
+% distinguish words with a different color, one may proceed like
+% so:---
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluacode}
+\begin{arab}
+wa-'at_A _dU 'l-qarnayni 'ummaTaN 'llatI hiya fI
+\LR{\textcolor{red}{\arb[fullvoc]{((ma.gribi 'l-^samsi))}}}
+wa-lA binA'a la-hum yu'amminu-hum mina 'l-^samsi.
+\end{arab}
+\end{arabluacode}
+% \iffalse
+%</example>
+% \fi
+%
+% \DescribeMacro{LRfootnote} \DescribeMacro{RLfootnote}
+% \cs{LRfootnote}\marg{text} and \cs{RLfootnote}\marg{text} typeset
+% left-to-right and right-to-left footnotes respectively in Arabic
+% environments. Unlike \cs{footnote}\marg{text}, the arguments of both
+% \cs{LRfootnote} and \cs{RLfootnote} are not expected to be Arabic
+% text. For example, \cs{LRfootnote} may be used to insert English
+% footnotes in running Arabic text:---
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluacode}
+\arb[fullvoc]{\cap{z}ayduN\LRfootnote{\enquote{Zayd
+is the son of ʿAmr}: the second noun is not in
+apposition to the first, but forms part of
+the predicate\ldots} "ibnu \cap{`amriNU}}
+\end{arabluacode}
+% \iffalse
+%</example>
+% \fi
+%
+% When footnotes are typeset from right to left, it may happen that
+% the numbers of the footnotes that are at the bottom of the page be
+% typeset in the wrong direction. For example, instead of an expected
+% number 18, one may get 81. \package{arabluatex} is not responsible
+% for this, but should it happen, it may be necessary to redefine in
+% the preamble the \LaTeX\ macro \cs{thefootnote} like so:---\\
+% \arabluaverb{\renewcommand*{\thefootnote}{\textsuperscript{\LR{\arabic{footnote}}}}}
+% \DescribeMacro{FixArbFtnmk} Another solution is to put in the
+% preamble, below the line that loads \package{arabluatex}, the
+% command \cs{FixArbFtnmk}. However, for more control over the layout
+% of footnotes marks, it is advisable to use the package
+% \package{scrextend}.\footnote{See
+% \url{http://ctan.org/pkg/koma-script}; read the documentation of
+% \package{KOMA-script} for details about the \cs{deffootnotemark} and
+% \cs{deffootnote} commands.}
+%
+% \DescribeMacro{setRL} \DescribeMacro{setLR} \cs{setRL} and
+% \cs{setLR} may be used to change the direction of paragraphs, either
+% form left to right or from right to left. As an example, an
+% easy way to typeset a right-to-left sectional title follows:---
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluacode}
+\setRL
+\section*{\arb{barzawayhi li-buzurjumihra bni 'l-buxtikAni}}
+\setLR
+\begin{arab}
+qAla barzawayhi bnu 'azhara, ra'su 'a.tibbA'i fArisa...
+\end{arab}
+\end{arabluacode}
+% \iffalse
+%</example>
+% \fi
+%
+% \paragraph{\package{reledmac}} The two-arguments command
+% \cs{edtext}\marg{lemma}\marg{commands} is supported inside
+% \cs{begin}|{arab}| \ldots\ \cs{end}|{arab}|. As an example, one may
+% get \package{arabluatex} and \package{reledmac} to work together
+% like so:---
+% \iffalse
+%<*example>
+% \fi
+\begin{arabluaverbatim}
+\beginnumbering
+\pstart
+\begin{arab}
+wa-ya.sIru ta.hta 'l-jildi
+\edtext{\arb{.sadIduN}}{\Afootnote{M: \arb{.sadIdaN} E1}}
+\end{arab}
+\pend
+\endnumbering
+\end{arabluaverbatim}
