`  == ``Reads like a manual``??? ==  Someone put a really weird tag on the ``how`` it works section on these lines. I have removed it - in fact I would very strongly question the whole idea of a tag like this, at the very least it needs to be applied with great discretion - articles are never improved by the addition of subjective opinion, based on a very highly personal reaction to text that has in fact been ``hammered`` out by a number of editors over a considerable period of time. In this case one might very well remark ``what the (naughty word expunged) do you expect it to read like?`` In Effect - this section IS a manual on how to construct a Roman numeral. This is altogether appropriate, as this is very probably exactly what the user is looking for. Ample space is given to the history of the Roman numerals, including the fact that they are very often ``mis-spelled``, and in fact that there is really no immutable ``standard`` way of writing them (one of their endearing quirks, this, one might well argue). On the other hand there is a ``usual`` way of writing them, which happens to be fairly logical and consistent, and one really needs to give this (in some form) before one can talk conherently about the exceptions!
