This directory was copied from github.com/googleapis/google-api-go-client/internal/gensupport. It is needed for the discovery client in ../generativelanguage.

To update, first clone github.com/googleapis/google-api-go-client into a directory we will call DIR below. Then, from the repo root:

rm genai/internal/gensupport/*.go
cp $DIR/internal/gensupport/*.go genai/internal/gensupport

Then edit the params.go and resumable.go files to replace the reference to internal.Version with the literal string from $DIR/internal/version.go, and remove the import of internal.
