Convert 4 (Man Page) to IPYNB (Jupyter Notebook)

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 IPYNB file extension stands for "Interactive Python Notebook" and is used exclusively with Jupyter Notebook. It is a JSON file format that contains a complete record of user sessions, including code, narrative text, equations, and visualizations. The IPYNB files facilitate reproducible research and easy sharing of data analysis workflows. Originating from the IPython project, Jupyter Notebook has expanded its capabilities to support multiple programming languages, making it a versatile tool in the data science and machine learning communities. The format's history traces back to the early 2010s when it was developed to enhance interactive computing and collaborative work.
