+A script for building the Rust compiler with the standard library for
+cross-building for PowerPC NetBSD.
+
+This script has only been tested on ArchLinux.
+
+# Dependencies
+
+```bash
+sudo pacman -S llvm rustup curl
+```
+
+# Build
+
+```bash
+./build.sh build
+```
+
+# Install
+```bash
+sudo ./build.sh install
+```
+
+# Link
+Link a rustup toolchain for use.
+```bash
+./build.sh link
+```
+
+To build a cargo project, ensure `.cargo/config` exists with the contents:
+```toml
+[target.powerpc-unknown-netbsd]
+linker = "powerpc--netbsd-gcc"
+```
+
+Then run `cargo +powerpc build --target=powerpc-unknown-netbsd`
