This directory contains the Grails application used to test SimpleCaptcha. It requires two libraries, included in the download: imaging.jar and simplecaptcha.jar. These need to be in the lib/ directory before the app will run. You can either copy them there, or create symbolic links to them if your OS supports it:    # ln -s ../../../../lib/imaging.jar .    # ln -s ../../../../dist/simplecaptcha.jar .Then to run:    grails run-appOnce it has started simply browse to:    http://localhost:8080/scThe source code used to generate these CAPTCHAs is available under:    grails-app/controllers/Most of these use the builder class, but one (SpringController.groovy) shows a simple example of configuring SimpleCaptcha using Spring. The corresponding Spring definition file is available located here:    grails-app/conf/spring/resources.groovyNote that this file uses Grails' DSL for configuring Spring managed beans. Information on Grails' Bean DSL is available here:    http://grails.org/doc/1.0.x/guide/14.%20Grails%20and%20Spring.html
