Convert 4 (Man Page) to MUSE

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.

The MUSE file extension, part of the Amuse Markup Language, is used for documents formatted with AmuseWiki. It simplifies document creation by using contextual markup rules for formatting. Developed by John Wiegley and maintained by Michael Olson, it aims to make document creation more intuitive. The extension is primarily used for creating and managing wiki pages and other text documents.
