Dear Franz,

MANY MANY thanks for your instructions!  They just worked! (except that I don't
have lndir, but I did for f in ../../src/algebra/*; do ln -s $f; done; instead)

They should definitively replace the old instructions on the wiki. In fact, I
think that both src_aldor2.tgz and your script should go into the fricas
contrib directory, say, contrib/aldor.  Maybe you could polish your script so
that it doesn't use lndir, detects ARCH automatically and does not depend on
the fricas source directory any longer.

ARCH is detected also in contrib/debian/mk_deb, you could steal it from there

The fricas source directory is used only to get axiom.sty, I think?  Maybe you
could just pack it into contrib too?

Here it is:

Don't ask me what it does, however :-)



Many thanks again,
