Here are the three prototypes of our method (WALO, LOIR and POTI), compiled with Java 1.6.

* "LOIR.zip": contains the LOIR prototype

* "POTI.zip": contains the POTI prototype, 
	+ by Thiago Abreu (thiagoa7@gmail.com)

* "WALO.zip": contains the WALO prototype
	+ by Cheikh Ba (cheikh.ba.sn@gmail.com)

* "scripts.sh": the bash scripts used to generate data input files used in our experiments (see below)

(3) How to run a prototype ?
##############################

Unzip the corresponding zip file somewhere in your disk.

** If you have JRE 1.6 or later: (see the README-[WALO | LOIR | POTI].txt file)
--------------------------------

** If not                      :
--------------------------------

	+ Go to the base directory with a terminal
	+ Delete all the .class files of the prototype (including subdirectories)

		* For Linux systems, call:    

			find . -type f -name *.class | xargs rm

	+ Compile the prototype with your Java version

		* Call:

			javac minicon/MiniConPref.java

	+ see the README-[WALO | LOIR | POTI].txt file

(4) A script to generate data: testcases.xml and preferences.xml files
#####################################################################

To run a script (linux systems)

	+ Go to the base directory with a terminal

	+ To make it runnable, call:
		
		chmod u+x script.sh

	+ To run it, call
		
		./script.sh
