-# Code coverage, the manual way:
-#
-# 1. Run `cargo install rustfilt` per the
-#    [code coverage docs](https://doc.rust-lang.org/rustc/instrument-coverage.html#building-the-demangler).
-# 2. You must manually run `rustup component add llvm-tools-preview` following
-#    the
-#    [coverge docs](https://doc.rust-lang.org/rustc/instrument-coverage.html#installing-llvm-coverage-tools).
-#    Per some searching, also run `cargo install cargo-binutils` to put these
-#    tools in the path.
-# 3. In Powershell, `$Env:RUSTFLAGS = "-C instrument-coverage"` then `cargo
-#    test`. When the tests run, record the name of the test binary.
-# 4. `rust-profdata merge -sparse default_*.profraw -o default.profdata`.
-# 5. `rust-cov show --Xdemangler=rustfilt
-#    target\debug\deps\code_chat_editor-4dbe5c7815a53cd9.exe
-#    --instr-profile=default.profdata --ignore-filename-regex=\\.cargo\\registry
-#    --format=html --output-dir=coverage`, replacing the binary path with the
-#    one recorded in step 3.
-# 6. Open the file `coverage\index.html`.
