#  THIS IS A SOURCE CODE FILE FROM A PROGRAM TO INTERACT WITH THE   #

# FROM THEIR REPOSITORY ( https://github.com/lbryio/lbry-sdk )      #
# WHICH I GONNA PRESENT TO YOU AS A BINARY. SINCE I DID NOT DEVELOP #
# IT AND I'M LAZY TO INTEGRATE IN A MORE SMART WAY. THE SOURCE CODE #
# OF THE SDK IS AVAILABLE IN THE REPOSITORY MENTIONED ABOVE.        #
#                                                                   #
