plugin

Package plugin provides a simple plugin interface by forking processes and using their stdout/stdin to enable communication between the parent process (main-component) and the child (plugin). This is inspired by how protoc and its various plugins work. Applications can read arguments, flags, and environment variables provided to the program to configure its behaviour, but then stream data from stdin to issue RPCs and write their responses to stdout.
