Convert WN to 2 (Man Page)

The WN file extension is associated with WriteNow, a word processor developed by NeXT for the original Apple Macintosh and NeXT workstations. WN files are text documents that often contain instructional manuals, worksheets, resumes, memos, or letters. WriteNow was released in 1984 and provided a simple, efficient way to create and edit text documents on early personal computers.

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.
