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`.
