Bug 33897 [Import/Export] Export to .tar.gz or .tar.bz2
Right click a Java project. Choose "Export...". A window opens where you can choose between different export targets. There is no ".tar.gz" target or ".tar.bz2". I would like to have either one (or both). If I must choose one, I prefer ".tar.bz2", but I don't really have a strong opinion about it; ".tar.gz" would be fine as well. The reason I somewhat prefer bzip2 is that bzip2 makes files noticably smaller than gzip, and my impression is that gzip is slowly being outcompeted. A Linux-GTK implementation would be good enough for me, but it is possible that "Unix All" would be a better platform as other Unix users could probably be interested in this as well.

* Standard workbench wizard for importing resources from a zip file
 * into the workspace.
 * <p>
 * This class may be instantiated and used without further configuration;
 * this class is not intended to be subclassed.
 * </p>
 * <p>
 * Example:
 * <pre>
 * IWizard wizard = new ZipFileImportWizard();
 * wizard.init(workbench, selection);
 * WizardDialog dialog = new WizardDialog(shell, wizard);
 * dialog.open();
 * </pre>
 * During the call to <code>open</code>, the wizard dialog is presented to the
 * user. When the user hits Finish, the user-selected zip file is imported
 * into the workspace, the dialog closes, and the call to <code>open</code>
 * returns.
 * </p>
