Windows NT/2000 has the concept of a Service Control Manager (SCM) which
is responsible for managing (e.g., starting, stopping, etc.) NT services
which are the equivalent of UNIX daemons. When a service is installed,
it can indicate to the SCM that it is dependent on one or more services.
The SCM will use this information to start/stop services in the right
order on system startup/shutdown or to automatically start a dependency
if it is not currently running. For example, the Cygwin PostgreSQL
(i.e., postmaster) service is dependent on cygipc's ipc-daemon service.
