//! Simple Syphon Client Example
//!
//! This example connects to a Syphon server and prints frame information.
//! Useful for testing basic Syphon functionality without the full application.
//!
//! Usage:
//!   cargo run --example simple_client -- "Server Name"
//!
//! If no server name is provided, it will list available servers and exit.
