// This build script is symlinked from each project that requires BLS's "fake crypto",
|
||
|
|
// so that the `fake_crypto` feature of every sub-crate can be turned on by running
|
||
|
|
// 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.
