   -p             use peer discovery (default: $PEER)
   -d             enable db support (default: $DB)
   -t             toggle txgen (default: $TXGEN)
   -D duration    txgen run duration (default: $DURATION)
   -m min_peers   minimal number of peers to start consensus (default: $MIN)

This script will build all the binaries and start benchmark and txgen based on the configuration file.

# exe, the dialog will only pop up once at the very first time.
# Also it's recommended to use `go build` for testing the whole exe.
