comparison Python/pythonrun.c @ 5850:6f67a1bda15a legacy-trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Moved some stuff here from main.c (part of a big restructuring - wait for more!). - The global flags that can be set from environment variables are now set in Py_Initialize (except the silly Py_SuppressPrint, which no longer exists). This saves duplicate code in frozenmain.c and main.c. - Py_GetProgramName() is now here; added Py_SetProgramName(). An embedding program should no longer provide Py_GetProgramName(), instead it should call Py_SetProgramName() *before* calling Py_Initialize().
