//! CLI interface to allow regex based file renaming

//! # Example:

//! ```bash

//! clear; el; carr -- '(C|c)argo.*(\..*)' --rep '$1ogra$2' --preview

//! clear; el; carr -- '(C|c)argo.*(\..*)' --rep '${1}ogra$2' --preview

//! ```

match app(&args) {

Ok(()) => Ok(()), // ensures that change to app success value isn't erased by call code

Err(e) => {

eprintln!("Error: {}", e); // bubling error will not pretty-print cause

std::process::exit(1);
