//! `apic` — API contract tooling.
//!
//! Binary entry point. The command-line interface and all subcommand handling
//! live in [`cli`]; everything below is wiring for the supporting modules.

/// Restores the default `SIGPIPE` disposition on Unix.

/// Rust installs `SIG_IGN` for `SIGPIPE` at startup, which turns a write to a
/// closed pipe (e.g. `apic read | head`) into a panic instead of a clean exit.
/// Resetting to `SIG_DFL` makes the process terminate quietly like a normal
/// Unix tool.
