Convert MDOWN to MS

The MDOWN file extension stands for "Markdown Documentation". It is used for files written in Markdown, a lightweight markup language with plain-text formatting syntax designed by John Gruber and Aaron Swartz in 2004. MDOWN files are commonly employed in software development to create readable and editable documentation, leveraging Markdown's simplicity for formatting text, lists, code blocks, and links. The historical significance of MDOWN lies in its facilitation of seamless documentation, enhancing clarity and accessibility across various platforms while remaining developer-friendly.

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.
