Hopefully someone else will come in and spruce it up :)  This
version is as simple as can be

lxc-snapshot -n a1
	create a snapshot of a1
echo "second commit" > /tmp/a
lxc-snapshot -n a1 -c /tmp/a
	create a snapshot of a1 with /tmp/a as a commit comment
lxc-snapshot -n a1 -L
	list a1's snapshots
lxc-snapshot -n a1 -L -C
	list a1's snapshots along with commit comments
lxc-snapshot -n a1 -r snap0 a2
	restore snapshot 0 of a1 as container a2

Some easy nice-to-haves:

1. sort snapshots in the list
2. allow a comment to be given in-line
3. an option to remove a snapshot?

Removing a snapshot can just as well be done with

	lxc-destroy -P /var/lib/lxcsnaps/c1 -n snap2

so I leave it to others to decide whether they really want
it, and provide the patch if so.
