I was looking at the standardized contracts page and was confused by the description for setSubRegistrar and subRegistrar.

Here's the description for setSubRegistrar: Records the name as referring to a sub-registrar at the given address.

I understand what a registrar is but am confused by the idea of a sub-registrar and was hoping someone could give a better explanation.

It allows for the creation of hierarchical name registrations.

Instead of just allowing you to register, for example, "foo" as being associated with one address, and "bar" with another, it would allow you to create a tiered name system, allowing for things like "foo/bar". (I think the idea was to make it more like DNS.)
