+
+VPP interface stats client
+==========================
+
+This is a source code and a binary of a ‘thin client’ to collect,
+aggregate and expose VPP interface stats through VPP stats socket API.
+It also provides some information about the installed VPP version.
+
+This can be used by monitoring systems that needs to grab those details
+through a simple executable client with no dependencies.
+
+example use case: where VPP runs in a container that can’t expose the
+socket API to the host level
