HOW TO RUN NETLOGO

- Windows users: Choose NetLogo from the Start menu.

- Mac users: Double click on the NetLogo 2.1 icon in the NetLogo
  folder.  (You may wish to drag this icon to the dock for easy
  access.)

- Other platforms: You must have Java 1.4.1 or higher installed;
  1.4.2 or higher is recommended.  You can download Java from
  http://java.sun.com/getjava/.  The method for starting the
  application may be different depending on your operating system
  and Java virtual machine.  You may be able to just double-click
  the NetLogo.jar file in your file manager.  Or, to start from
