-This go library handles the protobuf files
-and various functions for virtigo.
+They are what to use for starting droplets with virsh,
+but for making a cluster or "home cloud" with virtigo

-You must build the protobuf files using autogenpb
+When possible & sensible, use the same variable names as libvirt
+
+virtigo needs to coordinate all the virtual machine
+information centrally. The information in the libvirt xml
+files are imported into these protobuf definitions and
+passed around as protobufs
+
+virtigo recreates the libvirt xml files and calls
+'virsh create'
