I do seem to be able to find things that don't work as expected don't I.

The day before yesterday I thought to myself maybe I should look what 
Arch Linux does but never followed through on it. Thanks very much for 
the suggestion. I will give it a go and see how it goes. I will also 
compare it with the python3-flit module we have because that looks to 
use the pypproject.toml file, although there are several environment 
variables defined that I am not sure how to specify for my case but will 
see how things go.

We do have build but not installer. The python3-flit module seems to 
work without using installer, just build so will see how things go to 
start with only using build before looking at adding installer in as well.

Adolf.
