SYNOPSISunpack200 [ options ] input-file JAR-file
Options may be in any order. The last option on the command line super‐
sedes 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.

DESCRIPTIONunpack200 is a native implementation that transforms a packed file pro‐
duced by pack200(1) into a JAR file. Typical usage:
% unpack200 myarchive.pack.gz myarchive.jar
In this example, the myarchive.jar is produced from myarchive.pack.gz
using the default unpack200 settings.
