Hello,

This new option allows to specify additional variables to be inherited
in a “pure” (semi-pure?) environment.

The main motivation was the use of the SLURM batch scheduler, which
defines environment variables that you need to preserve so that things
like ‘mpirun’ work correctly.

Thoughts?

Ludo’.

Oh so I guess this is an improvement.  :-)

Something beyond --search-paths and etc/profile, right?  I’m not sure
what it would look like.

Thanks for your feedback David & Ricardo!
