## witharrows – “Aligned” math environments with arrows for comments

This package provides an environment `WithArrows` which
is similar to the environment `aligned` of amsmath (and mathtools), but gives 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.

The package requires the following other LaTeX packages: expl3, footnote, l3keys2e, tikz, and xparse.
