/// Example: Using SVGO CLI programmatically
///
/// This example demonstrates how to use the SVGO CLI library programmatically
/// in your Dart applications. While the primary usage is via command line,
/// you can also integrate it directly into your code.
///
/// ## Command Line Usage
///
/// After installing globally:
/// ```bash
/// dart pub global activate svgo_cli
/// ```
///
/// You can use the CLI directly:
/// ```bash
/// # Optimize a single file (overwrites input)
/// svgo input.svg
///
/// # Optimize to output directory
/// svgo -o dist input.svg
///
/// # Optimize multiple files
/// svgo icon1.svg icon2.svg icon3.svg
///
/// # Optimize all SVGs in a directory (using glob pattern)
/// svgo "src/**/*.svg"
///
/// # Multipass optimization
/// svgo -m input.svg
///
/// # Custom precision (2 decimal places)
/// svgo -p 2 input.svg
///
/// # Quiet mode (no output messages)
/// svgo -q input.svg
///
/// # Show help
/// svgo --help
///
/// # Show version
/// svgo --version
/// ```
