From 5425a2a8f808c92f23539d9bb862b1b942c3d39f Mon Sep 17 00:00:00 2001

Subject: [PATCH] virtme-ng: allow to run main commands directly from source

Provide helper scripts for the virtme-ng commands that can be executed
directly from the source directory (without necessarily installing
virtme-ng in the system).

This restores an old behavior of the legacy virtme that used to provide
such helpers.
