Basic steps of packaging
    1. Assigning a package abbreviation
    2. Defining a package instance
        Identifying a package instance
        Accessing the instance identifier in your scripts
    3. Placing objects into classes
    4. Making package objects relocatable
        Defining collectively relocatable objects
        Defining individually relocatable objects
    5. Writing your installation scripts
        Reserving additional space on the installation machine
    6. Defining package dependencies
    7. Writing a copyright message
    8. Creating the pkginfo file
    9. Creating the prototype file
        Creating the file manually
        Creating the file using pkgproto
    10. Distributing packages over multiple volumes
    11. Creating a package with pkgmk
        Package file compression
        Creating a package instance
        Helping pkgmk locate package contents
    12. Creating a package with pkgtrans
        Creating a datastream package
        Translating a package instance
