Convert TEXT MARKDOWNPHPEXTRA to 7 (Man Page)

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.

The 7 file extension refers to Unix manual pages (man pages) in Section 7 of the Unix manual, which covers miscellaneous system information. These files, such as "boot.7", provide documentation on various system components and conventions. Historically, man pages have been a fundamental part of Unix-like systems, offering essential guidance for system administrators and developers. To view a 7 file, use the "man" command, e.g., "man boot".
