Convert TXT MARKDOWNMMD to TEXI

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 TEXI file extension, short for Texinfo, is a documentation format used primarily by the GNU Project for creating software manuals. Developed by Richard Stallman and Bob Chassell, it organizes content into a book-like structure and allows a single source file to generate both online and printed documentation. TEXI files are widely used in open-source projects and are recognized by their TEXI extension.
