    (description
     "The name Pies (pronounced \"p-yes\") stands for Program Invocation
and Execution Supervisor.  This utility starts and controls execution of
external programs, called components.  Each component is a stand-alone
program, which is executed in the foreground.  Upon startup, pies reads
the list of components from its configuration file, starts them, and
remains in the background, controlling their execution.  If any of the
components terminates, the default action of Pies is to restart it.
However, it can also be programmed to perform a variety of another
actions such as, e.g., sending mail notifications to the system
administrator, invoking another external program, etc.

Pies can be used for a wide variety of tasks.  Its most obious use is to
put in backgound a program which normally cannot detach itself from the
controlling terminal, such as, e.g., minicom.  It can launch and control
components of some complex system, such as Jabberd or MeTA1 (and it
offers much more control over them than the native utilities).  Finally,
it can replace the inetd utility!")
