There is currently a wizard for creating a new library wrapper module.  You browse to find the JAR(s), it determines all
the packages within those JARs, creates the project.xml to mark all of those packages public and then it copies the JARs
to the module.  It works very nicely.

Usually library wrapper modules are created to support the use of third-party JARs in a project.  The platform
applications which use those JARs periodically want to upgrade those libraries.  AFAIK, there is no support in the UI
for doing that. It's a manual process that involves the developer removing the old JARs, copying in the new ones and
updating the project.xml to account for the changes.  Alternatively, I suppose one could delete the old wrapper module
and create a new one with the wizard, but then any other changes made to the original module would be lost.

Therefore, it would be great if there was a wizard for updating an existing library wrapper module.
