+# build-targets.sh — Build the El VM (elvm) for all supported platforms.
+#
+# Usage:
+#   ./build-targets.sh                    # build all targets
+#   ./build-targets.sh --list             # list targets and prerequisites
+#   ./build-targets.sh x86_64-apple-darwin  # build a specific target
+#
+# Prerequisites:
+#   - Rust toolchain (rustup) with cross-compilation targets installed
+#   - For Linux targets: cross-linkers (see comments below)
+#
+# Install a target:
+#   rustup target add <target>
+#
+# For cross-compilation from macOS to Linux:
+#   brew install FiloSottile/musl-cross/musl-cross
+#   # or use `cross` (https://github.com/cross-rs/cross):
+#   cargo install cross --git https://github.com/cross-rs/cross
