The files in the usblego.zip and how to run the program.

=====================================================
A. Description of the files:

main.pl  -- prolog program that packs indigolog.pl
            delivery.pl, and communicates with 
            JAVA through which it controls the 
            RCX

delivery.pl -- prolog program that contains the 
               action theory describing the rail
               way stations domain (actions, 
               fluents, effects of actions etc.)

golog.pl -- the indigolog system

railway.nqc  -- NQC program that implements 
                the basic actions specified in
                delivery.pl

*.nqh        -- some necessary constants for
                railway.nqc

Control.java -- JAVA program that facilitates 
                the communication between Indigolog
                (Eclipse) and the RCX (robot)

elevator.pl -- a sample 'no-RCX connection' program that
can be used to test a action theory and the GOLOG programs.
=======================================================
B. How to run the program:

1. Download railway.nqc to the RCX, press RUN on the RCX

2. Connect the USB to the computer, place the USB and the RCX 
so that the RCX can receive signals from the IR tower and vice
versa.

3. Start Eclipse and compile 'main.pl' 

[command: compile('main.pl')]

NOTE: -- path to the file might need to 
be specified

4. Run one of the 'main' goals in eclipse 

[command: main_test. 
or        main_control.]

5. On a COMMAND.COM windows: run 

java -Declipse.directory="...path to your eclipse directory here" Control
