Everyone, nice to meet you, hello, or it's been a while.

This book is a finishing-touch/revision to a photocopy book released at C81.

At the time I wasn't thinking of releasing a finished version, but a number of people wanted me to touch this up and release it, which honestly is a big relief for me, so thank you all so much so here it is.

The contents are the usual.

Without further ado, please enjoy.
