1//! Creates an archive from one or more input files.
2//!
3//! To create a new archive, run:
4//!
5//! ```shell
6//! cargo run --example create <path/to/output.a> <path/to/input1> <input2..>
7//! ```
8//!
9//! Assuming the output file doesn't already exist, this is roughly equivalent
10//! to running:
11//!
12//! ```shell
13//! ar -cr <path/to/output.a> <path/to/input1> <input2..>
14//! ```
