17             pack200(1) with an effort of 0. In this case the contents of  the

DESCRIPTION

26       unpack200 is a native implementation that transforms a packed file pro‐
27       duced by pack200(1) into a JAR file. Typical usage:
28
29       % unpack200 myarchive.pack.gz myarchive.jar
30
31       In  this  example, the myarchive.jar is produced from myarchive.pack.gz
32       using the default unpack200 settings.
33

40       output JAR file.

43
44       Removes the input packed file.
