Cool!  Well, I was tweaking and reviewing the series when…

…I see two issues about licenses:

 1. Metis 4 is not free software
 2. Scilab is Cecill v2.1 and not gpl2 as the patch suggests.

About #2, the fix is easy. :-)

About #1, it will be difficult.

Well, maybe these 3 old versions of Scilab could go to the channel
guix-science [1] or guix-science-non-free [2].

If Scilab 6 works with Metis 5, then there is no issue with the licenses
and could be included.

WDYT?
