// Before running this example, compile the `hello_world.rs` guest program with:
//
//   cargo risczero build --manifest-path examples/program_deployment/methods/guest/Cargo.toml
//
// Note: you must run the above command from the root of the `lssa` repository.
// Note: The compiled binary file is stored in
// methods/guest/target/riscv32im-risc0-zkvm-elf/docker/hello_world.bin
//
//
// Usage:
//   cargo run --bin run_hello_world /path/to/guest/binary <account_id>
//
// Example:
//   cargo run --bin run_hello_world \
//     methods/guest/target/riscv32im-risc0-zkvm-elf/docker/hello_world.bin \
