package registry
// Registry abstracts a registry that holds templates, which can be
// used in a Deployment Manager configurations. A registry root must be a
// directory that contains all the available templates, one directory per
// template. Each template directory then contains version directories, each
// of which in turn contains all the files necessary for that version of the
// template.
// For example, a template registry containing two versions of redis
// (implemented in jinja), and one version of replicatedservice (implemented
// in python) would have a directory structure that looks something like this:
// qualifier [optional] prefix to a virtual root within the repository.
// /redis
// /v1
// redis.jinja
// redis.jinja.schema
// /v2
// redis.jinja
// redis.jinja.schema
// /replicatedservice
// /v1
// replicatedservice.python
// replicatedservice.python.schema
type Type struct {
Collection string
