Convert 1 (Man Page) to MS

The 1 file extension refers to Unix Section 1 Manual Pages, which are plain text files containing documentation for user commands in Unix systems. Accessed via the "man" utility, these files provide detailed information on command usage, options, and examples. Historically, they have been an essential part of Unix documentation, helping users understand and effectively utilize commands. The 1 designation indicates that the manual page pertains to general commands.

The MS file extension, short for "Manuscript", is associated with the roff (runoff) document formatting system used in Unix-like operating systems. It is part of the GNU roff (groff) implementation, which formats documents such as letters, memoranda, reports, and books. Historically, it evolved from the Multics runoff system in the 1960s and became integral to Unix documentation. The MS macro package supports features like cover pages, table of contents, numbered headings, and multi-column layouts.
