And a nice one it is. Can it be installed in its own prefix? Sorry, I 
never have, so I don't know the proper incantations -- I don't see a 
setup.py, but I haven't investigated further.

Yes, we could all write in assembly, too. Not to be too whiny, but 
expecting everyone to do interesting things with sed in their makefiles 
as a matter of course is not very reasonable. Some users don't even know 
how to write a makefile. And very few know how to extract a few values 
from a file from within a makefile without relying on an external 
script. I do, but I'm thinking about others who'd have to do similar 
things in the future (e.g., have a pile of code in which petsc is one of 
many external dependencies).
