Convert TEX to 2 (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.

A 2 file extension refers to a Unix manual page (man page) that documents a specific system call. These files are part of the Section 2 of the Unix manual, which is dedicated to system calls. Each 2 file is named after the system call it describes, such as "link.2" for the "link" system call. These files are intended to be viewed using the "man" utility in Unix-based systems. Historically, they have been a fundamental part of Unix documentation, providing detailed information on how to use system calls, their return values, possible errors, and related manual pages.
