been migrated over to the new organization. Where we
would have previously had an 'ldap' node terminus at
puppet/indirector/node/ldap.rb, we would not have it at
puppet/indirector/ldap/node.rb, and it would be a subclass
of puppet/indirector/ldap.rb.
These are called terminus classes, and there are now three
categories of them: The base class itself, abstract classes
that provide most of the functionality (e.g., the ldap and
yaml classes), and the classes themselves that implement
the functionality for a given model like Node or Facts.
The base terminus class handles auto-loading any of these
classes from disk.
