-# This prepares a custom sysroot with our custom `alloc` instead of
-# the standard one.
-#
-# This requires several hacks:
-#   - Unlike `core` and `alloc`, `std` depends on more than a dozen crates,
-#     including third-party crates that need to be downloaded, plus custom
-#     `build.rs` steps. Thus hardcoding things here is not maintainable.
-#   - `cargo` knows how to build the standard library, but it is an unstable
-#     feature so far (`-Zbuild-std`).
-#   - `cargo` only considers the use case of building the standard library
-#     to use it in a given package. Thus we need to create a dummy package
-#     and pick the generated libraries from there.
-#   - The usual ways of modifying the dependency graph in `cargo` do not seem
-#     to apply for the `-Zbuild-std` steps, thus we have to mislead it
-#     by modifying the sources in the sysroot.
-#   - To avoid messing with the user's Rust installation, we create a clone
-#     of the sysroot. However, `cargo` ignores `RUSTFLAGS` in the `-Zbuild-std`
-#     steps, thus we use a wrapper binary passed via `RUSTC` to pass the flag.
-#
-# In the future, we hope to avoid the whole ordeal by either:
-#   - Making the `test` crate not depend on `std` (either improving upstream
-#     or having our own custom crate).
-#   - Making the tests run in kernel space (requires the previous point).
-#   - Making `std` and friends be more like a "normal" crate, so that
-#     `-Zbuild-std` and related hacks are not needed.
