Managing base and other snappy apps

[Charles Butler]

As a side note the webdm snap exists as a front end to snaps for snappy and
managing them.

It's a great resource for you to model after for your own front end. Hope
this helps, I'm pretty fresh on my voyage with snappy my self.

If you need additional help I know the fine people in #snappy on freenode
are a great complimentary companion to this mailing list.

All the best,
