// This package is for validating all the README files present in the Registry
// directory. The expectation is that each contributor, module, and template
// will have an associated README containing useful metadata. This metadata must
// be validated for correct structure during CI, because the files themselves
// are parsed and rendered as UI as part of the Registry site build step (the
// Registry site itself lives in a separate repo).
