NOTES

This command should not be confused with the unpack command. They are distinctly separate products.

The Java SE API Specification provided with the JDK is the superseding authority in case of discrepancies.

EXIT STATUS

The following exit values are returned: 0 for successful completion, and a value that is greater than 0 when an error occurred.
