//! CLI module for bssh
//!
//! This module provides command-line interface parsing for bssh, including:
//! - Standard bssh CLI (`Cli`)
//! - pdsh compatibility layer (`pdsh` submodule)
//!
//! # Architecture
//!
//! The CLI module is structured as follows:
//! - `bssh.rs` - Main bssh CLI parser with all standard options
//! - `pdsh.rs` - pdsh-compatible CLI parser for drop-in replacement mode
//!
//! # pdsh Compatibility Mode
//!
//! bssh can operate in pdsh compatibility mode, activated by:
//! 1. Setting `BSSH_PDSH_COMPAT=1` environment variable
//! 2. Symlinking bssh to "pdsh" and invoking via that name
//! 3. Using the `--pdsh-compat` flag
//!
//! See the `pdsh` module documentation for details on option mapping.
