From 5f9dcff39d5e25c6bef30d569e405635633f3c69 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Mon, 1 Aug 2016 04:59:13 +0200 Subject: VPP Python language binding - plugin support - Moved Python generator tool to tools directory - Added build-vpp-api Makefile target - Generator now only creates a Python representation of the .api the rest of the framework is in the vpp_papi script - Each plugin has its own namespace. - Plugin Python files are installed in vpp_papi_plugins for easy use inside the build tree.
