//! High-level Subversion client operations.
//!
//! This module provides the [`Context`](crate::client::Context) type and related functionality for performing
//! Subversion client operations such as checkout, update, commit, diff, merge, and more.
//!
//! # Overview
//!
//! The client module is the primary interface for applications that need to interact with
//! Subversion repositories as a client. It provides high-level operations that handle
//! authentication, conflict resolution, and other complex workflows automatically.
//!
//! ## Core Operations
//!
//! - **Repository operations**: checkout, update, switch, relocate
//! - **Working copy modifications**: add, delete, copy, move, mkdir
//! - **Committing changes**: commit with callbacks and revision properties
//! - **Querying**: status, log, info, list, cat
//! - **Comparison**: diff (between revisions, URLs, or working copy)
//! - **Merging**: merge with conflict detection and resolution
//! - **Properties**: get, set, list both versioned and revision properties
//! - **Maintenance**: cleanup, vacuum, upgrade
//!
//! # Example
//!
//! ```no_run
//! use subversion::client::Context;
//!
//! let mut ctx = Context::new().unwrap();
//!
//! // Checkout a repository
//! ctx.checkout(
//!     "https://svn.example.com/repo/trunk",
//!     "/path/to/working/copy",
//!     None, // HEAD revision
//!     true, // recursive
//! ).unwrap();
//!
//! // Get status of working copy
//! ctx.status("/path/to/working/copy", None, true, false, false, false, false, false, |status| {
//!     println!("{}: {:?}", status.path().display(), status.node_status());
//! }).unwrap();
//! ```
