[PATCH 13/18] trace-cmd: Move python-related files in python/

From: Vladislav Valtchev (VMware)
Date: Wed Dec 20 2017 - 13:10:04 EST


This patch moves all the files related with trace-cmd's python support to a
dedicated directory, as part of a bigger restructuring plan of trace-cmd's code
base. The build system has been updated to support this new directory structure
by adding a separate Makefile in python/ and by making the parent Makefile to
invoke it.
