//! Creates an example Brittle repository with realistic academic references.
//!
//! For references that have freely available PDFs (arXiv preprints and open
//! author copies), the script downloads the PDF and attaches it to the
//! reference. Downloads that fail are skipped with a warning so the seed
//! always completes even without network access.
//!
//! Usage:
//! brittle-seed [PATH]
//!
//! PATH defaults to `~/brittle-example`. The directory must not already
//! contain a git repository.
