External netlet

The program which booted a node and is seen by the node as a specially privileged netlet.

A node does not have any user interface, and it does not have any direct access to the outside world. This would make it rather difficult to control, and even to boot, hence the external netlet. An external netlet is therefore any ordinary application which happens also to be a netlet-- it can boot the node and has other administration control over it. Since the external netlet is an ordinary program it has the usual access to system resources, unhindered by the node's security.

External netlets are how a Jtrix node can be embedded in another application.
