// Program http demonstrates how to set up a JSON-RPC 2.0 server using the
// github.com/creachadair/jrpc2 package with an HTTP transport.
//
// Usage (see also the client example):
//
// go build github.com/creachadair/jrpc2/tools/examples/http
// ./http -listen :8080
//
// The server accepts RPCs on http://<address>/rpc.
