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`.
