Legacy system notes
I used to collate my system notes in BML. It is a powerful tool for typesetting multi-layered bidding structures. However, I also yearn interconnectivity in Markdown. Markdown has hyperlinks. I can break down my systems into reusable chapters and then link them together.
The below are my legacy system notes built with BML. I keep them here for now because I have not yet fully covered them in this book. I will eventually remove them when the migration is complete.
