unpack200 - JAR Unpacking tool

## SYNOPSIS

f4unpack200f2 [ f2options ] f2input-file f2JAR-file

Options may be in any order. The last option on the command line supersedes all previously specified options.

input-file Name of the input file, which can be a pack200 gzip file or a pack200 file. The input could also be JAR file produced by pack200(1) with an effort of 0. In this case the contents of the input file will be copied to the output JAR file with the Pack200 marker.

JAR-file Name of the output JAR file.

## DESCRIPTION

f2unpack200 is a native implementation that transforms a packed file produced by f2pack200(1) into a JAR file. Typical usage:

f2% unpack200 myarchive.pack.gz myarchive.jar

In this example, the f2myarchive.jar is produced from f2myarchive.pack.gz using the default f2unpack200 settings.

## OPTIONS

Sets the deflation to be f2true, f2false, or f2keep on all entries within a JAR file. The default mode is f2keep. If f2true or f2false, overrides the default behavior and sets the deflation mode on all entries within the output JAR file.

f4-r --remove-pack-file

Removes the input packed file.

f4-v --verbose

Outputs minimal messages. Multiple specification of this option will output more verbose messages.

f4-q --quiet
