Convert TXT MARKDOWNMMD to MDOWN

The MultiMarkdown Documentation (MMD), stored with a TXT file extension, is designed for text documents formatted in MultiMarkdown syntax. The MMD format streamlines the conversion of plain text into various formats such as HTML, PDF, and LaTeX, essential for professional documentation. Introduced in 2005 by Fletcher T. Penney, MMD enhances traditional Markdown by supporting additional features like tables, footnotes, and citations, optimizing documents for better readability and usability in diverse technical environments.

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.
