 	I have nothing against that. The command above sounded really
 	simple to me that it wouldn't need a separate @ command. But
 	why not.

 	Ok, what you meant is now clearer to me. I have no good idea of
 	how this exactly works but IIRC i've seen sysutils/pkg_install
 	whose job must be to "solve" this problem. I think we have kind
 	of version, with packing list format version. I need to dig into
 	this. I've only seen a little part of pkg_install actually.

 	I just wanted to add @conf feature because ports lacks some
 	guidelines concerning how to handle configuration, where to
 	put sample, and I needed that support in pkg_install before
