Non, détrompez-vous, ce n'est pas vraiment une doc, parce que
les codes des modules du fraktalisme est en perpétuelle évolution.
# La doc (enfin !)
## Points 3d
Bientôt les quaternions ?
## Xperiment
## Portable Net Map
Des trucs bizarres, qui migreront (un jour, peut-être...) vers
d'autres modules.
## Fractint color mapfile
This is juste a [wip](fractcolmap.f90), stay tuned.
