Convert TEXT MARKDOWN to TEXINFO

A TEXT file extension, associated with Markdown Documentation, which simplifies writing and formatting text for web and technical documentation. Markdown, created by John Gruber in 2004, facilitates easy-to-read, plain-text documents that can be converted to HTML. It's essential for developers and writers to create structured documents quickly and efficiently, enhancing productivity and readability without complex code.

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.
