ANNOUNCE: POE-Component-GCS

This package is titled a "Generic network server
model" and is based on a pattern that I call
"Server / Controller / Subprpocess". This is a very
useful pattern that consists of these components:
a network server interface,
a process manager to queue/schedule/run processes
a set of child processes that asynchronously
perform long-running tasks

Add to that a command-driven interface, and a piece
that can run quick "housekeeping type" tasks without
having to start a child, and this becomes the starting
point for a lot of possibilities.

While this is based on an abstraction of a pattern, it
contains a completely usable and functional configuration.
See the 'demo' subdirectory and the README therein for
a quickstart example and some hints for extending this
package in various ways.
