Ce wiki regroupe les résultats de mes expériences en informatique accumulés au cours de mes recherches sur le net.

Dans la mesure du possible, j'ai cité mes sources ; il en manque certainement… :-)

 +=== HOW TO RUN ===
 +
 +For running this installer, in the application "Terminal" type:
 +"/pathToThisFolder/install-uninstall.sh"
 +
 +For a list of programs installed like this type:
 +ls /etc/install-uninstall
 +
 +
 +=== PURPOSE ===
 +
 +This installer is mostly for trying out the software
 +If you end liking it, ask someone how to package it
 +
 +If your system includes the app "pacman", you can get those packages at:
 +https://gitlab.com/es20490446e/express-repository/-/wikis/home
