Application Packaging Developer's Guide

The class Field

The class field names the class to which an object belongs. Using classes is an optional package design feature. This feature is discussed in detail in Writing Class Action Scripts.

If you do not use classes, an object belongs to the none class. When you execute the pkgmk command to build your package, the command inserts the CLASSES=none parameter in the pkginfo file. Files with file type i must have a blank class field.
