/**
 * A builder for {@link ArgsFormat} instances.
 *
 * Use the methods in this class to dynamically build {@link ArgsFormat}
 * instances. When you are done configuring the builder, call
 * {@link getFormat()} to build an immutable {@link ArgsFormat}.
 *
 * For convenience, you can call {@link ArgsFormat::build()} to create a new
 * builder and use its fluent API to configure and build a format:
 *
 * ```php
 * $format = ArgsFormat::build()
 *     ->addCommandName(new CommandName('server'))
 *     ->addCommandOption(new CommandOption('add', 'a'))
 *     ->addArgument(new Argument('host'))
 *     ->addOption(new Option('port', 'p'))
 *     ->getFormat();
 * ```
 *
 * You can optionally pass a base format to inherit from. The arguments of the
 * base format are prepended to the arguments of the built format. The options
 * of the base format are added to the built options:
 *
 * ```php
 * $baseFormat = ArgsFormat::build()
 *     ->addOption(new Option('verbose', 'v'))
 *     ->getFormat();
 *
 * $format = ArgsFormat::build($baseFormat)
 *     // ...
 *     ->getFormat();
 * ```
 *
 * Read {@link ArgsFormat} for a more detailed description of args formats.
