How to use
Import the Packager application in your XWiki using the Import tool in the Administration and point your browser to the Package.WebHome page.
From there you can create a package and define it. The important field is the filelist field which lists all the package's wiki pages (one per line).
Once your package is defined you can Export it to a "xar" file using the Export link.
Next steps for this application is to include a file picker to create the file list by selecting files from the wiki.
