Convert 6 (Man Page) to TEXT MARKDOWNPHPEXTRA

The 6 file extension refers to Unix Section 6 Manual Pages, which document games and screensavers in Unix-based systems. These manual pages, accessible via the "man" command, provide instructions and details about various entertainment programs. Originating from the Unix Programmer's Manual developed by Dennis Ritchie and Ken Thompson in 1971, these files offer insights into text-based and graphical games, such as "fortune", "cowsay", and "tetris".

The TEXT file extension, associated with PHP Markdown Extra Documentation, refers to plain text files used to write and store documentation. These files are simple, human-readable, and can be easily converted to HTML using Markdown syntax. The TEXT extension is commonly used for README files, configuration files, and other documentation purposes. Markdown Extra enhances the basic Markdown syntax with additional features like tables, footnotes, and definition lists, making it a powerful tool for creating well-structured documentation.
