Convert TEXT MARKDOWNPHPEXTRA to MUSE

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 MUSE file extension, part of the Amuse Markup Language, is used for documents formatted with AmuseWiki. It simplifies document creation by using contextual markup rules for formatting. Developed by John Wiegley and maintained by Michael Olson, it aims to make document creation more intuitive. The extension is primarily used for creating and managing wiki pages and other text documents.
