Only for 64-bit Linux:

p2ptrade doesn't work properly, this build is just to check whether it
works in general.

You need local bitcoind to run it.
1. on testnet, it requires txindex
2. on mainnet, it might work without txindex, but is faster with txindex

Here's how to set it up on testnet:

1. run bitcoind or bitcoin-qt with txindex, e.g:
    ./bitcoind -testnet -txindex -daemon
    If you previously ran it without txindex, you need to use reindex
option one time only:
    ./bitcoind -testnet -txindex -reindex -daemon
    Wait until it downloads/reindexes blocks.

2. Configure ngcccbase to use testnet:
   ./ngccc-cli setval testnet true

4. From now you can use either command-line version:
    ./ngccc-cli --help
   Or GUI:
    ./ngccc-gui

5. If you need several instances, it's better to copy whole ngccc
directory and delete wallet.db in the copy so new wallet will be
created.
   (It is also possible to use different wallet files, e.g.
./ngccc-cli -wallet=testnet.wallet, but it doesn't work properly if
you use them simultaneously due to color.db locks.)
