The LaTeX extension `witharrows` is distributed under the LPPL 1.3 license.
## Presentation
-This extension has been written by F. Pantigny (`fpantigny@wanadoo.fr`).
-
The LaTeX package `witharrows` provides environments `{WithArrows}` and `{DispWithArrows}`
similar to the environments `{aligned}` and `{align}` of `amsmath` but with the possibility to draw arrows on the right side of the alignment. These arrows are usually used to give explanations concerning the mathematical calculus presented.

+% \subsubsection{The construction of the preamble of the \textbackslash halign}
+%
+% The control sequence |\@@_construct_halign:| will ``start'' the |\halign| and
+% the preamble. In fact, it constructs all the preamble excepted the end of
+% the last column (more precisely: except the part concerning the construction
+% of the left node and the right node).
+%
+% The same function |\@@_construct_halign:| will be used both for |{WithArrows}|
+% and |{DispWithArrows}|.
+%
+% Several important points must be noted concerning that construction of the
+% preamble.
+% \begin{itemize}
+% \item The construction of the preamble is done by reading backwards the
+% format |\l_@@_format_str| and adding the corresponding tokens in the input
+% stream of TeX. That means that the part of the preamble concerning the last
+% cell will be constructed first.
+% \item The function |\@@_construct_halign:| is recursive in order to treat
+% succesively all the letters of the preamble.
+% \item Each part of the preamble is created with a |\use:x| function. This
+% expansion of the preamble gives the ability of controlling which parts of the
+% code will be expanded during the construction of the preamble (other parts
+% will be expanded and executed only during the execution of the |\halign|).
+% \end{itemize}
