Convert TEXT MARKDOWNPHPEXTRA to CTX

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 CTX file extension is associated with the ConTeXt Markup Language, a typesetting system used for creating structured documents. It is primarily utilized for document layout and design, offering advanced typographic features and flexibility. ConTeXt was developed by Hans Hagen and Ton Otten in the early 1990s as an alternative to LaTeX, aiming to provide a more integrated and user-friendly approach to document preparation. The CTX file format is part of this system, enabling the creation of high-quality, publication-ready documents.
