var Build string

Build sets the dcnt build id using git's SHA Version sets the semantic version number of the build $ go install -ldflags "-X github.com/DCNT-Hammer/dcnt/engine.Build=`git rev-parse HEAD` -X github.com/DCNT-Hammer/dcnt/engine.=`cat VERSION`" It also seems to need to have the previous binary deleted if recompiling to have this message show up if no code has changed. Since we are tracking code changes, then there is no need to delete the binary to use the latest message

type IManagerPlugin 

type IManagerPlugin struct {

This has two methods: Server must return an RPC server for this plugin type. We construct a IManagerPluginRPCServer for this.

Client must return an implementation of our interface that communicates over an RPC client. We return IManagerPluginRPC for this.

Ignore MuxBroker. That is used to create more multiplexed streams on our plugin connection and is a more advanced use case.
