# This is Bitcoin_No_Dev_Fee_Tool, support all use stratum protocol miner, such as eth, etc, zec, sc.
# 
# We use pydivert (https://pypi.python.org/pypi/pydivert/2.0.1) capture and inject miner network packet 
# with user bitcoin address replacing dev address.
# 
# usage: python python no_dev_fee.py {coin_adress} {stratum_port}
# eg: python no_dev_fee.py t1T3Q9rdqR8jWk4g7yaWoDKa2dcyG8QLcgU 3329
#
# package exe: pip install pyinstaller
# pyinstaller no_dev_fee.py -F -i logo.ico
#=============================================================================
# !Notice before package, we must modify C:\Python27\Lib\site-packages\pydivert\windivert_dll\__init__.py 35 line
# In this way, we can load WinDivert64.dll in current path avoid pyinstaller dll bug.
#
# if platform.architecture()[0] == "64bit":
#     #DLL_PATH = os.path.join(here, "WinDivert64.dll")
#     DLL_PATH = "WinDivert64.dll"
# else:
