Ian Wienand fa3c5e3056 Add image size report 
In the common case of not specifying a size, we are already running
"du" over the image to figure out how big it is.  Leverage that by
saving it's output and displaying a pruned list of big files when
requested.

We add a flag to show a summarised option (files >10MiB) and another
to show full output, should you wish that level of detail.

"Invocation" documentation is updated (and formatted a little better
while we're here).

Image building tools for OpenStack

diskimage-builder is a flexible suite of components for building a wide-range of disk images, filesystem images and ramdisk images for use with OpenStack.

This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.

For example:

$ DIB_RELEASE=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntu

will create a bootable Ubuntu Trusty based qcow2 image.

diskimage-builder is useful to anyone looking to produce customised images for deployment into clouds. These tools are the components of TripleO that are responsible for building disk images. They are also used extensively to build images for testing OpenStack itself, particularly with nodepool. Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
