Inital commit built using latex makebst. Future modifications likely to be manual.
To use simply include \bibliographystyle{leeds-hps} before the usual \bibliography{my-bib-file} for generating a bibliography (goes without saying, compile twice). You only need the leeds-hps.bst file.
Built specifically for Summer 2024. May have changed if you are seeing this in the future.
