This repo exists purely to maintain and host a remastered copy of Vaughan Pratt's original 1973 paper, Top Down Operator Precedence. Contributions are very welcome.

A PDF copy of the original paper was freely available from hall.org.ua, but it recently went offline. Thankfully, it can still be accessed through to the Wayback Machine.

Thanks to Brian Campbell, David Majda, Corentin Smith and Brett Handley for their contributions and helpful input.
