# USAGE: INTEGER = CreateHexFile(FILENAME, [CONTENT])
# This function creates a file and writes bytes in binary mode.
# The bytes have to be provided as a string or list of
# hexadecimal numbers. Each byte must be formatted as
# a 2-digit hexadecimal number.
#
# The function returns 1 on success or 0 on error.
#
# The following example creates a file and writes "ABC"
# NULL-terminated string into the file:
#
#     CreateHexFile("testing.txt", " 41 42 43 00 ")
#

        # Detect Python version by doing a simple division and
        # looking for the remainder. Python 2 always drops the
