xmindltd/xmindmark ? reverse-engineered prompt

Build me a small TypeScript project called XMindMark that lets people write mind maps in plain text and convert them into real mind map files. I want a simple syntax that feels a lot like markdown, where a main topic can have indented or nested bullet style children, and then the tool can turn that text into a .xmind file. It should also be able to export to SVG, and work both as a command line tool and as a JavaScript library I can import in another app.

Make the CLI easy to use with a file path or pasted text from standard input, and let me choose the output format and output folder. Please include a basic example in the README and a few sample files so I can see how the syntax works. If you need to look up current docs online for anything related to the file format or rendering, go ahead.
