PCManager
---------

This is an application which makes use of two of the 
IAgent-based intelligent agents.  It represents an
example of the utility of autonomous, but not necessarily
intelligent agents.

The main points of this application include:

* The PCManager application allows a user to perform 
  two major functions	- set Alarms to go off at 
			  specified times or intervals.
			- set Watches on files or 
			  directories.

* Each ALarm represents an instance of an autonomous
  'TimerAgent'.  The 'TimerAgent' spins its own Thread 
  and then goes to sleep once for a one-shot alarm, or
  repeatedly for an interval alarm.

* Each Watch represents an instance of an autonomous 
  'FilerAgent'.  The 'FileAgent' spins its own Thread 
  and then goes to sleep for 15-second intervals. When
  it wakes up, it checks the state of the target file 
  or directory.

To see the application in action you have to compile the 
application java file using:  

	javac PCManager.java

and produce 23 class files, apart from the 3 IAgent base 
classes, resulting with:

IAgent.class
PCManager.java
AlarmDialog.java
WatchDialog.java
FileAgent.java
TimerAgent.java
IAgentEvent.java
ExecuteDialog.java
AlertDialog.java
IAgentEventListener.java
