Built with efficiency in mind, it enables quick parsing and analysis of large log files with minimal overhead.\n\n## Features overview\n\n* __[Automatic Pager Integration](#automatic-usage-of-pager)__: Automatically integrates with a pager for enhanced convenience, defaulting to [less](https://greenwoodsoftware.com/less/) if available, but fully supporting any compatible pager.\n* __Log Streaming Mode__: Enable log streaming with the `-P` flag, which disables the pager.\n* __[Field-Based Filtering](#filtering-by-field-values)__: Filter log records by key/value pairs using the `-f` option, with support for hierarchical keys.\n* __[Level Filtering](#quick-filtering-by-log-level)__: Easily filter logs by level with the `-l` option.\n* __[Timestamp Range Filtering](#filtering-by-time-range)__: Filter logs by timestamp range using the `--since` and `--until` options with intuitive formats:\n  * RFC-3339 timestamp format.\n  * Current configured timestamp output format (via the `-t` option or environment variable).\n  * User-friendly shortcuts like `today`, `yesterday`, `friday`, or relative offsets such as `-3h` or `-14d`.\n* __[Field Visibility Control](#hiding-or-revealing-selected-fields)__: Quickly hide or reveal specific fields using the `-h` option.\n* __Empty Field Hiding__: Automatically hide empty fields with the `-e` flag.\n* __Field Expansion__: Control multi-line field and message formatting with the `-x` option:\n  * `never`: Compact single-line output with escaped newlines.\n  * `inline`: Preserve newlines as-is in the output.\n  * `auto`: Automatically expand fields containing multi-line content.\n  * `always`: Expand all fields into structured multi-line format.\n* __[High-Speed Message Sorting](#sortin",
