same project, from scracth with new goals

The old version was too complex and not so easy to use, but it had good
ideas. I like the KISS philosophy and the "Arch Way" (see
https://wiki.archlinux.org/index.php/The_Arch_Way_v2.0). I want to make
the new tigre engine really easy (almost stupid), following the KISS
principles (see README for more infos on this).
