 *
 * The tracking jobs do the actual work of configuring tracking on the
 * target machine. Tracking jobs may have *styles*, variations depending
 * on the distro or environment of the target system. At the root of
 * each family of tracking jobs (installation, machine, user) there is
 * a class with static method `addJob()` that takes the configuration
 * information from the relevant Config sub-object and optionally
 * adds the right job (subclass!) to the list of jobs.

 *
 * The install-tracking job (there is only one kind) does a GET
 * on a configured URL with some additional information about
 * the machine (if configured into the URL).

 * No persistent tracking is done.
