Pies: Program Invocation and Execution Supervisor for Managing External Programs

The name Pies (pronounced 'p-yes') stands for Program Invocation and Execution Supervisor.

This utility starts and controls execution of external programs, called components.

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.
