Ruby

Vagrant is a tool for building and distributing development environments.

Vagrant::Config::VersionBase.finalize

This is called just before configuration loading is complete of
a potentially completely-merged value to perform final touch-ups
to the configuration, if required.

This is an optional method to implement. The default implementation
will simply return the same object.

This will ONLY be called if this is the version that is being
used. In the case that an `upgrade` is called, this will never
be called.
