templates looks like:

/home/ubuntu/random-hash-code-path/heat.yaml:

......
type: subtemplate.yaml
......

And there is a subtemplate.yaml file in the same directory.

But the path is not the same as go program working directory, so I will get a error which tells me cannot find subtemplate.yaml.

So I tried to edit the stacks.Template.TE.Files (which is a map[string]string), like: {"subtemplate.yaml", "heat_template_version: "2013-05-23"..........."}

But I found it was overwrite to empty when executing stack.Create, so I got the same error.

Is there anyway to use sub template?

plus: the openstack HOT package is uploaded by our users, so the name of subtemplate.yaml is just a example, not certain file name.
