+par moi-même (et peut-être, un jour, d'autres gens...) et qui risquent

+Nous allons commencer par des fonctions inventées lors d'une *n*-ième session
+du projet [ExplodeVidz](ExplodeVidz.md).

+# libtthimage, la doc
+
+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. 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.
+Je vous conseille de vérifier leurs pertinences, et en particulier
+les options `-p` et `-pg` que j'oublie parfois d'enlever avant
+le _push_.
+
+Le script [build.sh](../build.sh)  tente d'automatiser les
+compilations de la bibilothèque, des tests et des outils
+en ligne de commande. Il est encore loin d'être parfait.
+
+## 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
+
+??? *Insérez ici quelques exemples d'utilisation des tools.*
