And not to forget Cython, which is the only static Python compiler that is widely used. Compiles and optimises Python to C code that uses the CPython runtime and allows for easy manual optimisations to get C-like performance out of it. http://cython.org/ Stefan -- http://mail.python.org/mailman/listinfo/python-list
