* system's tools for managing zip files.
|
*
|
* This tool is a stand-alone program since it is run in preparation for a
|
* off line upgrade and runs using the current program's jars rather than
|
* the new build's jars as is manditory for the Upgrader itself. Since this
|
* tool itself is run using the old bits prior to upgrade and the upgrade
|
* itself is dependent upon this tool, it should be kept simple and stable
|
* to insure that the upgrade will work.
