+# vendoring, but it doesn't.
+# The adopted solution is to somehow use the crate contents from
+# a directory given via the mozbuild config, or bootstrapped.
+#
+# Unfortunately, doing `include!(mozbuild::windows_rs_path!("src/lib.rs"))`
+# in the crate's lib.rs doesn't work because of
+# https://github.com/rust-lang/rust/issues/66920.
+#
+# Previous versions of the windows crate had submodules declared
+# directly in lib.rs. Annotating each of them with
+# `#[path = concat!(mozbuild::windows_rs_path!("path/to/mod.rs"))]`
+# unfortunately also didn't work, because of
+# https://github.com/rust-lang/rust/issues/48250.
+#
+# Thankfully, newer versions of the windows crate now only have an
+# `include!` at the end of lib.rs, so we can get away with simply
+# replacing it with an `include!` that uses `mozbuild::windows_rs_path!`.
+#
+# We ensure that the in-tree contents match what we expect based on
+# the original crate.
+# The expectations are as such:
+# - Cargo.toml is identical to the original one with the addition of the
+# following two lines at the end (after an empty line):
+# [dependencies.mozbuild]
+# version = "0.1"
+# - src/lib.rs is mostly identical to the original one, with two notable
+# differences:
+# - the addition of `#![allow(warnings)]` on the first line, because if
+# the crate had been vendored normally, it would not be affected by
+# `-D warnings`, and `#![allow(warnings)]` mimicks that.
+# - the replacement of any
