Like its namesake from the Emacs world, package Advice implements a generic framework for extending the functionality of selected commands and environments. This package was developed as an auxiliary package of [Memoize](https://ctan.org/pkg/memoize). This is why it is, somewhat unconventionally, documented alongside that package. This applies to both the manual and the documented code listing. # LICENCE This work may be distributed and/or modified under the conditions of the LaTeX Project Public License, either version 1.3c of this license or (at your option) any later version.
