voirs-cli 0.1.0-rc.1

//! Binary packaging and distribution system for VoiRS CLI.
//!
//! This module provides comprehensive packaging functionality for distributing
//! the VoiRS CLI across multiple package managers and platforms. It includes:
//!
//! - Binary optimization and packaging
//! - Package manager integration (Homebrew, Chocolatey, Scoop, Debian)
//! - Update management and distribution
//! - Cross-platform packaging pipeline
//!
//! ## Features
//!
//! - **Binary Packaging**: Optimized binary generation with compression and validation
//! - **Multi-Platform Support**: Packages for macOS, Windows, and Linux distributions
//! - **Package Managers**: Native integration with popular package managers
//! - **Update System**: Automated update checking and distribution
//! - **Validation**: Comprehensive package validation and integrity checking
//!
//! ## Example
//!
//! ```rust,no_run
//! use voirs_cli::packaging::{PackagingPipeline, PackagingOptions};
//!
//! # async fn example() -> anyhow::Result<()> {
//! let options = PackagingOptions::default();
//! let pipeline = PackagingPipeline::new(options);
//! let packages = pipeline.run_full_packaging().await?;
//! println!("Generated {} packages", packages.len());
//! # Ok(())
//! # }
//! ```
