What is the purpose of using a configuration file like phpdoc.xml in a PHP project?

Using a configuration file like phpdoc.xml in a PHP project allows developers to customize the documentation generated by PHPDocumentor. This file specifies settings such as which files or directories to include or exclude from documentation generation, the output format, and any additional tags or annotations to include in the documentation. By using a configuration file, developers can control how their code is documented and ensure that the generated documentation meets their specific requirements.
