Dear PETSc team, ? I have been recently reading about SCons, www.scons.org. May I know how does?it compare to your other options? They claim that their build system is completely portable and coded in pure?python. We are in process of preparation for a new project, so I have been following your discussions on build systems and revision control softwares. ? Best regards, Farshid Mossaiby

It would be easy to convert between being spread out in the makefiles and being held in some central location. ?For instance, something like builder.py, run at the end of configuration time, could instead of building the project, write a single tupfile [1] for all of PETSc, and then we could rejoice with fast correct builds, even after reconfiguring. I think the metadata itself belongs with the implementations (more or less where it is currently) unless we are actually working with an image-based system (which does not look likely in the near future). It looks like tup only has a Linux daemon, so it would run the same as make everywhere else. That does not seem like a strong enough case to use it. Why not just write the same thing in portable Python? We do need to run everywhere. ?? Matt ?
