Dubious hack of a Holmakefile rule for building ordinals.pdf
Use an infix back-quote as syntax for IMAGE (à la Isabelle).
Make \lambda typeset a bit better.
Make multiplication and less-than typeset better.
Use new \holthmenv command to make complex HOLthm-setting easier.
Add comment about ordinal operations working like :num analogues.
Add short section on division and modulus.
Make \exists and \mid typeset better.  (Less/more space respectively.)
Explain exponentiation notation confusion better.
Add a proof for the div/mod theorem.
Improve choice of variable names in cancellation theorem for *
Really typeset \mid properly.
Better variable names for lt_omega.
Minor refinements of div/mod material.

- state uniqueness theorem with equalities flipped
- include associativity as a dependency in proof
Explain list notation.
A good beginning to the description of Cantor Normal Form.
