You can have instances of a package on one site, each with a different URL and different permissions, all sharing the same code and tables. This requires that a package be developed package-aware. You'll see how to do that +<<<<<<< tutorial-newpackage.html in this tutorial.
Browse to http://yourserver.test:8000/admin/applications/application-add/.
Choose "My First Package" from the list and click OK (the other fields are optional).
By mounting the package, we've caused all requests to http://yourserver.test:8000/myfirstpackage to be satisfied from the files at /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/myfirstpackage/www.
The remainder of the tutorial walks you through each file one at a time as you create the package. You can skip all this, and get a working package, by doing the following:
