++### Supported build tags
++
++- `containers_image_openpgp`: Use a Golang-only OpenPGP implementation for signature verification instead of the default cgo/gpgme-based implementation;
+ the primary downside is that creating new signatures with the Golang-only implementation is not supported.
++- `containers_image_ostree_stub`: Instead of importing `ostree:` transport in `github.com/containers/image/transports/alltransports`, use a stub which reports that the transport is not supported. This allows building the library without requiring the `libostree` development libraries.
++
++ (Note that explicitly importing `github.com/containers/image/ostree` will still depend on the `libostree` library, this build tag only affects generic users of …`/alltransports`.)
