// This build script is symlinked from each project that requires BLS's "fake crypto",

// with FAKE_CRYPTO=1 from the top-level workspace.
// At some point in the future it might be possible to do:
// $ cargo test --all --release --features fake_crypto
// but at the present time this doesn't work.
