Convert MDOWN to TEXINFO

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 Texinfo is a documentation format developed by the GNU Project, created by Richard Stallman and Bob Chassell. It uses plain text files with @-commands to generate both online and printed documentation from a single source. Texinfo files, with the TEXI extension, support various output formats like HTML, PDF, and Info. This system simplifies maintaining consistent documentation across multiple formats.
