Convert TEXT MARKDOWNPHPEXTRA to TXT MARKDOWNMMD

The TEXT file extension, associated with PHP Markdown Extra Documentation, refers to plain text files used to write and store documentation. These files are simple, human-readable, and can be easily converted to HTML using Markdown syntax. The TEXT extension is commonly used for README files, configuration files, and other documentation purposes. Markdown Extra enhances the basic Markdown syntax with additional features like tables, footnotes, and definition lists, making it a powerful tool for creating well-structured documentation.

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.
