Thanks for adding BibTeX libraries to the test suite.
A library is added as a shallow git submodule named {owner}-{repo}:
git submodule add <repo-url> {owner}-{repo}
git config -f .gitmodules submodule.{owner}-{repo}.shallow true
git add .gitmodules {owner}-{repo}If a GitHub URL points at a single .bib file, add the whole repository (not just
the file).
Then add a row to the table in README.md, keeping it sorted
alphabetically by path. If the library has 5 or fewer BibTeX files, deep-link each
file; otherwise show the count. Note that some libraries use the .bb extension.
The exact conventions an automated agent follows are documented in
CLAUDE.md.
