Convert TXT MARKDOWN to 9 (Man Page)

Markdown Documentation files, often stored with a TXT extension, are utilized for writing plain-text formatted documents that are easy to read and convert to HTML. Originating in 2004 by John Gruber and Aaron Swartz, Markdown's intent was to create a simple syntax for writing web-based documents. It is widely adopted in software development, documentation, and content management systems due to its readability and ease of use. These files facilitate collaborative work and version control, making them indispensable in modern IT workflows.

The 9 file extension refers to Section 9 of the Unix manual pages, specifically covering Kernel Routines. These manual pages provide detailed information on kernel APIs, internal structures, and other essential aspects of kernel development. Developed by Dennis Ritchie and Ken Thompson at AT&T Bell Laboratories in 1971, Section 9 is crucial for kernel developers but is not universally available due to its specialized nature.
