// A crate which builds the `backtrace` crate as-if it's included as a
// submodule into the standard library. We try to set this crate up similarly
// to the standard library itself to minimize the likelihood of issues when
// updating the `backtrace` crate.

extern crate alloc;

// We want to `pub use std::*` in the root but we don't want `std` available in
// the root namespace, so do this in a funky inner module.

}

// This is the magical part which we hope works.
