Overview

Reads the vcpkg registry's versions database from the checkout the updater image ships.

versions/<letter>-/<port>.json lists every published version of a port, newest first, along with the scheme it was published under. versions/baseline.json at a given commit gives the version floor that commit sets for every port.
