+// Package socketclient is a pure Go implementation of adapter.VppAPI, which uses
+// unix domain sockets as the transport for connecting to the VPP binary API.
+//
+// The current implementation only supports VPP binary API, the VPP stats API
+// is not supported and clients still have to use vppapiclient for retrieving stats.
+//
+//
+// Requirements
+//
+// The socketclient will connect to /run/vpp-api.sock by default. However this
+// is not enabled in VPP configuration by default.
+//
+// To enable the socket in VPP, add following section to VPP config.
+//
+//	socksvr {
+//		default
+//	}
