  But there's no need for the return ("Why do I need a 'return' in a
configuration file?").  A configuration file like:

	name       = "A Blog Grows in Cyberspace"
	basedir    = "$HOME/source/boston/journal"
	webdir     = "$HOME/source/boston/htdocs"
	lockfile   = webdir .. ".modblog.lock"
	url        = "http://www.example.com/blog/";
	author     = { name = "Joe Blog" , email = "joe@example.com" }
	timezone   = "-8:00"
	adtag      = "programming"
	debug      = false
	conversion = "html"

doesn't have to end up setting a bunch of globals:

	config = {}
	f = ("config.file","t",config)
	f()

	print(config.name) -- Tadaaaaaah!
