How can I package a python script and modules into a single script?

Unfortunately, Raedler's boot script closes stdin, which is a fairly
big limitation.
The herefile in the shell script (END_OF_PYTHON_CODE) redirects stdin
before
python starts; stdin is closed at the end of the herefile. This
disables raw_input()
and anything else that reads sys.stdin. Enter the following at a shell
prompt
to demonstrate the problem:
        python - << HEREFILE
        > print raw_input("Enter something")
        > HEREFILE
You will get the following error:
        Enter somethingTraceback (most recent call last):
          File "<stdin>", line 1, in ?
        EOFError: EOF when reading a line

But all is not lost. The "zipheader.unix" script can be rewritten to
use the '-c' option of python
instead of stdin and a herefile. This also handles the case where
Python may be even less
than version 2.0. This works the same. Just "cat zipheader.unix
main.zip > main" then run "main".
