# A script to convert blob from the MS spec to array of byte to use in unitary tests
#
# 00000000 c7 01 00 01 20 54 e2
# 00000008 c7 01 00 01 20 54 e2
# taken from the spec, will give:
# 0xc7, 0x01, 0x00, 0x01, 0x20, 0x54, 0xe2,
# 0xc7, 0x01, 0x00, 0x01, 0x20, 0x54, 0xe2,
#
# Notes:
# * the script reads the two first lines to detect the number of items per lines, so you need a blob with at least 2 lines
# * the script detects if items are hex values by searching for + or -
#
# sample usage:
# $ python scripts/specBytesToCode.py < image.txt > image.c
# then go edit image.c and paste that in your code
