I'm trying to use the Gentran package (./share/maxima/5.12.0/share/contrib/gentran) but I don't manage to load it into Maxima. There is no .mac file, only .lisp files which I tried to load one by one but it doesn't work too.
Does somebody know how to load it please?
Thanks.
PS : I'm using the 5.12.0 version of Maxima (wxMaxima)
