Convert 9 (Man Page) to RST

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.

The RST file extension stands for reStructuredText, a lightweight markup language widely used for technical documentation. Originally developed as part of the Docutils project in 2001, reStructuredText facilitates the creation of readable plaintext documents that can be easily converted into various output formats such as HTML, PDF, and LaTeX. Its clear syntax and straightforward conventions make it a preferred choice for documenting software projects, especially within the Python community. RST files serve a crucial role in maintaining accessible and well-structured documentation, ensuring consistency and simplicity in formatting across different platforms.
