Is there any way to install template/plugin/module in one pack. There are many options to install extensions/plugins/modules http://jeffchannell.com/Joomla/install-multiple-joomla-extensions-in-a-single-package.html http://digitalvariants.blogspot.com/2011/01/installing-multiple-joomla.html
as single install but simply none and no way to do this when installing a Joomla! template
Joomla 1.6+ support packages which allow you to combine several zip's for extensions etc into a single zip package.
