## Don't trust those hex blobs?
Compile the payloads yourself with `payloads/build-n-print.sh` on a Debian host (Debian 13 tested).
You'll need to `apt install nasm python3 binutils-aarch64-linux-gnu binutils-arm-linux-gnueabihf` then run the script from in the payloads directory. It will compile each payload and output the zlib compressed hex strings. Compare those to what is in `main.go` (or replace them with your own) and build the `copyfile-go` binaries with `goreleaser build --snapshot --clean` from the main project directory.
