Packaging enables you to control what elements will be included in the cartridge SAR file that you will deploy to the ASAP environment. The cartridge packaging instructions appear as a list of all types of elements that can be packaged inside the cartridge. By default, everything within the cartridge project will be included when the cartridge is built. If you want to specify specific entities to include for each type of element (service actions, atomic actions, and so forth), select the element type in the first column to display all entities of this type in the Entity column. See "Packaging Projects" for more information.
