Each instance of a package can have paramaters associated with +it. These are like preferences, and they can be set by the +administrator for each application to change the behavior of your +application.
To add parameters for your package, go to the Automatic Package +Manager (/acs-admin/apm)
Click on your package
Under the Manage section, click on Parameters
It's fairly self-explanatory at this point. Create the +parameters you want, and then access them in your code using the +parameter::get procedure.
