[I'm not aware it's dead, though it doesn't in install straightforwardly
from CPAN as far as I remember. It's used by the Gridwise Tech Globus
integration referenced by the SGE Globus Howto.]

I've ranted about that here before from experience with it in jobmonarch
in particular. (If there's a useful definition of the XML emitted --
which at least in the past hasn't even been valid -- I'd still be
interested to know.) Anyhow, qstat -xml isn't my idea of an API or a
scalable solution to the problem. It certainly hasn't been stable to
the extent that the normal qstat output has been.
