Hello,
may I interrupt from the user perspective:
I see two classes of users:
(i) with system installation (/usr/local etc.)
(ii) with local installation
And for class (ii) the default place where to put any
auxiliary files etc. should be the installation directory.
With all what you say below it seems you are considering only
class (i) --- while class (ii) users definitely don't want
/temp or their home directory cluttered with auxiliary files/directories
(that's why they created a local installation).
So shouldn't it be the case that when prefix is set during build,
then the installation directory obtains a new sub-directory, say,
aux, and everything goes there?
(Or else there should be a clear build-option for doing so.)
Oliver
P.S. As I said, this is written from the (future) user perspective
(the affine package is of interest to me; though yet the documentation
was to unspecific to me so I didn't get what's it precisely about
(and what is the difference to the grobner-package)).
