//! Shared building blocks for the Pimalaya command-line tools.
//! Published for internal Pimalaya usage: the API follows the needs of
//! its consumers (himalaya, neverest, cardamum, calendula and friends)
//! and may change without notice. Third parties should treat it as
//! private; the io-* protocol crates and pimalaya-stream are the
//! supported surface.
//!
//! This crate factors out the pieces every Pimalaya CLI would
//! otherwise reimplement: argument parsing glue, output rendering,
//! logging, interactive prompts and the account setup wizards. Each
//! piece sits behind its own cargo feature, so a binary pulls in only
//! what it uses.
//!
//! Unlike the io-* protocol libraries this crate is deliberately std:
//! it exists to talk to a terminal, a filesystem and a human, so it
//! never targets no_std.
//!
//! The clap module wires shared arguments and the completion, manual
//! and JSON Schema commands into a binary's parser. The printer and error
//! modules render command output, events and failures to stdout, the
//! output module holds the shapes every binary shares (bytes, pages),
//! and the log module initializes the logger. The prompt, spinner and table
//! modules handle interactive input and formatted output, and the
//! validator module holds reusable value parsers. The wizard module
//! collects account settings per protocol (IMAP, SMTP, JMAP, CalDAV,
//! CardDAV), each protocol behind its matching feature. The build
//! module exposes helpers for build scripts.
