I have forked BTCGPU from their git repo, I have made quite a few changes to the code, the biggest of which is the name switching from bitcoin to bitcoingold it was a lenghty task but thanks to that the application outputs are now bitcoingold-cli, bitcoingold-tx etc instead of bitcoin-cli which would just casue conflicts for most or overwrite their existing bitcoin-cli. meaning you can now run BTG alongside BTC without having to faff around with changing data dir for the apps, blockchain etc
I will be making my commit very soon once done I will have to see if they accept or not.
Thanks
