-* [`gb4e-emulate.sty`](gb4e-emulate.sty): For S&P-style rendering of examples using `gb4e` syntax. We encourage the use of `expex` for examples; `gb4e-emulate.sty` is only provided to typeset papers where the author chose to use `gb4e`.
-* [`sp-logo.pdf`](sp-logo.pdf): the S&P logo
-* [`sp-hyperxmp.sty`](sp-hyperxmp.sty): a package to add metadata to the PDFs produced

-The logo file and sp-hyperxmp.sty are only needed for the final typeset, when the S&P production team is ready to publish a paper. Authors do not need these files.
