Hi Deimi and all, My idea is to adapt l3build system for tex4ht needs.
I think using l3build for test infrastructure is all to the good. But we don't really want/need a copy of build.lua in the repo, do we? Did you have to modify it? I can't tell if the differences from the distributed version are just different versions, or something you needed to do. I see it somehow avoids testing the date line? If so, that alone is an excellent reason to use it :). Thanks much, Karl
