Embedding Python in C++

[Jethro Ma]

Here is what I have:
....
pName = PyString_FromString("btdownloadheadless");
pargs = PyString_FromString("argv = 'foo.torrent'");
PyImport = PyImport_ImportModuleEx
("btdownloadheadless",pargs, pargs, 0);
....

I have a feeling my pargs is wrong. How do I make it so that it is
the equivalent of typing

btdownloadheadless.py --responsefile=foo.torrent

in the command line
