Announcement text: 
----------------------------------------------------------------------
Canoniclayout is a small extension to the memoir document
class that allows to design a canonic layout based of the
great circle inscribed within the page and tangent to the
horizontal sides of the text block rectangle. The margins
reflect the trimmed page shape ratio, therefore the page
block principal diagonal coincides with the corresponding
page diagonal; this layout is especially good for ISO shapes
but can be used with many other traditional book page shapes.
