  - gzip -d archive.tgz -> turn it into archive.tar
  - tar -xf archive.tar -> un-archive it
- how to add a man directory to the manual :
  - cp man/man1 /usr/local/share/man/man1 (create man1 if necessary)
  - mandb
- i didn't use any of both library above but the one for linux : https://github.com/42Paris/minilibx-linux (there are pbm with their man pages)
