contrib/nm-live-vm: set of scripts for building a live initramfs for NM testing

The scripts use Fedora to build a Fedora 18 (i386) live image, and pack
it into a single self-extracting script, that can be easily distributed.

$ sudo ./build [-n name] [-b branch/commit]
will create name-bundle.sh with NM built of a specified NM branch(commit).
(defaults are: name="nm-live-vm"; branch="master")

Resulting nm-live-vm-bundle.sh can be run with almost any distro.
The only requirement is qemu-kvm (and VNC (tigervnc) on RHEL).

+NetworkManager live VM scripts
+------------------------------
+
+This set of scripts can be used to build a live initramfs image suitable
+for testing NetworkManager in a virtual environment. The scripts themselves
+are intended to be used by a power user who can adapt them to their needs.
+The result, on the contrary, is intended to be used by anyone who wants to
+play with NetworkManager on the command line.
+
+Building the initramfs image:
+
+sudo ./build.sh [-n name] [-b branch/commit]
+
+You may have to update ./build.sh to suit your distribution. The included
+is prepared for Fedora 18 and the image is also build using Fedora 18
+repositories.
+
+Then you can distribute the self-extracting archive and run in on other machines:
+
+./nm-live-vm-bundle.sh
