default behavior and sets the deflation mode on all entries
within the output JAR file.

-r –remove-pack-file
Removes the input pack file.

Displays minimal messages. Multiple specifications of this
option displays more verbose messages.

of the options described on the reference page for the Java
application launcher. For example, -J-Xms48m sets the startup
memory to 48 MB. See java.

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.
