I have provided a short overview to explain what the purpose of the type is
from the users point of view:
(There is potentially a lot more documentation to follow of course).

Naturally any comments,views and criticisms are appreciated.

One important point that is not mentioned in the above link is that
 implementation of the type (which I am now reasonably sure is practical )
is eminently suitable as a (practical realworld robust etc) platform for the
techniques currently being developed at boost.
The 'prototype' for a physical-quantity type , the inbuilt type, provides
formidable competition.

As to the Wiki. I have resolved to postpone that at the moment,
(finite time.. I will have to spend a lot of time to work out most effective
use of Wiki)
 and concentrate on trying to explain what I think are the basic mechanisms
in more (non implementational) detail.

Whether this project will blossom or fizzle out I don't know,
but I would like to thank everyone who has participated
 in the recent Physical Quantities and Dimensional Analysis threads.
I now have a much clearer view of what this thing is
... which I will attempt to convey in due course.
