# for a private `group/subgroup/project` with subpackage path `subpackage`, GitLab will respond
# as if the user is looking for project `group/subgroup`, with subpackage path `project/subpackage`.
# Since `go get` doesn't authenticate by default, this means that
# `go get gitlab.com/group/subgroup/project/subpackage` will not work for private projects.
# `go get gitlab.com/group/subgroup/project.git/subpackage` will work, since Go is smart enough
# to figure that out. `import 'gitlab.com/...'` behaves the same as `go get`.
