Easy enough: ~$ mkdir pkg ~$ touch pkg/__init__.py ~$ vim pkg/__main__.py ~$ cat pkg/__main__.py import pkg.whatever ~$ vim pkg/whatever.py ~$ cat pkg/whatever.py import sys import pkg.__main__ as main cmdline = [sys.executable, '-m', main.__package__] + sys.argv[1:] print(cmdline) ~$ python -m pkg ['q:\\tools\\Python27\\python.exe', '-m', 'pkg'] ~$ python -m pkg arg1 arg32 ['q:\\tools\\Python27\\python.exe', '-m', 'pkg', 'arg1', 'arg32'] I don't really understand what your spec is. Why do you need to inspect this information from sys.argv? Can you not just always use 'python -m pkg' as your entry point? Oscar -- http://mail.python.org/mailman/listinfo/python-list
