 #! /bin/bash
+#
+# Publishes all four parry crates (parry2d, parry3d, parry2d-f64, parry3d-f64)
+# to crates.io using a single `cargo publish --workspace` invocation.
+#
+# Why this script exists
+# ----------------------
+# All four crates share a single source tree at `<repo>/src`, referenced from
+# each crate's manifest as `path = "../../src/lib.rs"`. That path points outside
+# the crate directory, which `cargo publish` refuses to package.
+#
+# To work around it *only during publishing*, this script temporarily:
+#   1. rewrites each crate's `[lib] path` from `../../src/lib.rs` to `src/lib.rs`, and
+#   2. creates a `src` symlink in each crate pointing at the shared `../../src`.
+#
+# Cargo follows the symlink and bundles the real source into each `.crate`, so
+# native workspace publishing works. A trap restores the manifests and removes
+# the symlinks on exit (including on error or Ctrl-C), leaving the tree as it was.
+#
+# Extra arguments are forwarded to `cargo publish`, e.g.:
+#   ./publish.sh --dry-run
+#   ./publish.sh --token "$CARGO_TOKEN"
+#
+# Requires cargo >= 1.90 (for `cargo publish --workspace`).
