Les fichiers HTML que vous avez ici sont des versions historiques,
Les fichiers [HTML](html/) que vous avez ici sont des versions historiques,
qui seront peut-être mise à jour au prochain grand refactoring.
Leur contenu est donc à prendre avec des pincettes, ymmv.
Ceci dit, les principes généraux sont encore bons...
Ceci dit, les principes généraux sont encore bons. Mais il y a quelques
points à préciser.
## Compilation
Certaines options de compilation sont dans le fichier de
[paramètres](../Paramakes.mk) pour les différents fichiers make.
Le script [build.sh](../build.sh) tente d'automatiser les
compilations de la bibilothèque, des tests et des outils
en ligne de commande.
## Installation
Le script [install.sh](../install.sh) va installer divers fichiers
aux bonnes places là où on lui dit avec la variable `DESTDIR`.
Attention, celle-ci doit être cohérente avec les valeurs déclarée
dans le fichier Paramakes.mk !
## Utilisation
