[Mesa-users] Change_E_flag

[Bill Paxton]

time for some detective work.   look in star/test_suite from the old version to find cases that use the old control name (use_hydrodynamic_surface_BCs) in their inlists.

then look at the corresponding inlists in the newer version to see what has taken its place.

let us know what you discover.
