simple1/ project.xml src/ java/org/sakaiproject/tool/simple/ SimpleTool.java webapp/ web.xml tools/ sakai.sample.tools.simple.xml
To conform to Sakai 2.2. best practice, this should be:
simple1/ simpl1-tool tool project.xml src/ java/org/sakaiproject/simple/tool/ SimpleTool.java webapp/ web.xml tools/ sakai.sample.tools.simple.xml
