16 input-file
17 Name of the input file, which can be a pack200 gzip file or a
18 pack200 file. The input can also be JAR file produced by
19 pack200(1) with an effort of 0, in which case the contents of

27 The unpack200 command is a native implementation that transforms a
28 packed file produced by pack200(1) into a JAR file. A typical usage
29 follows. In the following example, the myarchive.jar file is produced
30 from myarchive.pack.gz with the default unpack200 command settings.
31
32 unpack200 myarchive.pack.gz myarchive.jar

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