// Conditionally include the notes if:

// - we're in stage 2 of the build.
// The latter point prevents a really silly and annoying problem,
// where the location of ".." is different depending on whether we're
// building the crate for real, or whether we're in build.rs
// generating the lookup tables (in which case we're relative to the
// location of build.rs, not lib.rs, so the markdown file appears
// missing).
