While we are unable to offer any unconditional guarantee that everything
here is totally wrong, that should be a reasonably safe assumption.
An addendum contains various material
too long to fit in the main text.
It includes homework exercises and their solutions, computer algorithms,
some detailed proofs omitted from the paper, and heaps of scrap.
is Reid's Magma start-up file, included for the
considerable inconvenience of the reader. Suffer!
This file gives some
sample calculations and baby applications
to orbifold del Pezzo surfaces.
old is a historical folder containing reams of scrap.
