	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
	I can write my patch for

	I'm quite interested in pkg_install, I think there could be
	a lot of interesting things to add. I'll probably try to add
	such a purge command later.
