Not sure, if that's what you mean, but writing a self-replicating
script is easy too:

import os
import sys

with open(os.path.abspath(__file__)) as myself:
    with open(sys.argv[1], "w") as yourself:
        yourself.write(myself.read())


Give it a filename as a command-line argument and it will write
itself to that file.
