Convert TXT MARKDOWN to TEXI

Markdown Documentation files, often stored with a TXT extension, are utilized for writing plain-text formatted documents that are easy to read and convert to HTML. Originating in 2004 by John Gruber and Aaron Swartz, Markdown's intent was to create a simple syntax for writing web-based documents. It is widely adopted in software development, documentation, and content management systems due to its readability and ease of use. These files facilitate collaborative work and version control, making them indispensable in modern IT workflows.

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.
