Petr, can you describe a bit about how tooling works in Fort, so we all
have a better idea of the challenges involved?  I see the sources have a
layout similar to clang.  Is it reusing any clang code directly?

What is the status of Fort?  What standard(s) does it support and what
is planned for future standard support?  Does it support a working
subset of Fortran?  Does it provide a Fortran runtime library or does it
use existing runtimes?  Any OpenMP support?

Anything else we should know about Fort?
