| 34 | ** |
| 35 | ** This code calls the MetroWerks shared-library initialization code |
| 36 | ** and performs one extra step: it remembers the FSSpec of the file |
| 37 | ** we are loaded from, so we can later call PyMac_AddLibResources to |
| 38 | ** add the file to our resource file chain. |
| 39 | ** |
| 40 | ** This file is needed for PythonCore and for any dynamically loaded |
| 41 | ** module that has interesting resources in its .slb file. |
| 42 | ** Use by replacing __initialize in the "CFM preferences" init field |
| 43 | ** by __initialize_with_resources. |
