Convert TEX to 4 (Man Page)

TEX is the file extension for TeX documents, a typesetting system used for creating professional-quality documents, primarily in academic and technical fields. It was developed by Donald Knuth in the late 1970s to improve the appearance of mathematical and scientific papers. TeX is known for its precision and ability to handle complex formatting. LaTeX, built on top of TeX, simplifies document creation by providing a set of macros and templates for common document structures, making it easier to produce consistent, high-quality output.

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.
