In this function, there is:

if (!value || !*value)
	return error("%s: lacks value", var);

but in some places an empty string is not an error, and in some other places 
we "die" in case of error instead of using "return error..."
So I am not sure this function can be generally usefull as it is now.

Maybe I should add a flag parameter to control if we should "die" or "return 
error" and if we should accept an empty string or not.

What do you think ?

Christian.
