*: begin incorporating the "validate" subcommand

Browse source 
Update the README to show the validate subcommand by default.
This doesn't eliminate the default behavior of _not_ using the command,
but begins the visibility of using it by default.

Also copy one of the existing tests, to ensure the same behaviour works
as we add more subcommands and/or global flags.
