[Mesa-users] Changing metallicity for binary stars

One detail is, if you try to create a model with a different metallicity by
creating new pre main sequence models, that won't work very well fro
binary. Mostly because your pre-main sequence models will have extreme
overflow for most close binaries.

You can check the test_suite case $MESA_DIR/binary/test_suite/double_bh,
where inlist1 and inlist2 have a relaxation to a different metallicity.
This is done via options in star_job.
