| 5 | ! ------- |
---|
| 6 | ! Check to see if the atmospheric specific heat capacity and |
---|
| 7 | ! mean molar mass for the gas mixture defined in gases.def |
---|
| 8 | ! corresponds to what we're using. If it doesn't, abort run |
---|
| 9 | ! unless option 'check_cpp_match' is set to false in |
---|
| 10 | ! callphys.def. |
