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