Convert 4 (Man Page) to XML

The 4 file extension refers to Unix Section 4 Manual Pages, which document special files and device drivers. These files, such as "mouse.4", describe how devices interact with the Unix operating system and are accessed using the "man" utility. Historically, these manual pages have been a fundamental part of Unix documentation, helping users understand and manage system devices.

XML, or Extensible Markup Language, is a widely used file extension in computer technology. It is designed to store and transport data, enabling structured information exchange between different systems. XML files are both human- and machine-readable, making them versatile for various applications, including web services, configuration files, and data storage. Originating in the 1990s, XML was developed by the World Wide Web Consortium (W3C) to simplify data interchange and ensure platform independence. Its flexibility and extensibility have made it a standard in many IT environments, fostering seamless integration and data sharing across diverse platforms.
