#Version 0.1.1
#Info: Installs GoByte daemon, Masternode based on privkey.
#GoByte Version 0.1.12.1 or above
#Tested OS: Ubuntu 17.04, 16.04, and 14.04
#TODO: make script less "ubuntu" or add other linux flavors
#TODO: remove dependency on sudo user account to run script (i.e. run as root and specifiy gobyte user so gobyte user does not require sudo privileges)
#TODO: add specific dependencies depending on build option (i.e. gui requires QT4)
