The README claims vmware_fusion support, but this doesn't seem to be correct

[adamwight]

Maybe this is a misunderstanding, but I was hoping this would work:

vagrant plugin install vagrant-vmware-appcatalyst
export VAGRANT_DEFAULT_PROVIDER=vmware_fusion
vagrant up

Instead,

The provider 'vmware_fusion' could not be found, but was requested to
back the machine 'default'. Please use a provider that exists.
