Editing RTF files in text mode

I have a bunch of CLI-only computers (I have not bothered to set up a GUI yet). I'm comfortable enough in the CLI to not NEED a GUI for most things. However, as a student, turning in Plain-Text documents really doesn't cut it. Is there a way to edit Rich Text Format (.rtf) files from a CLI without popping into a GUI? I'd just need justification (Right, Left, Center), bolding, italics, and a bit of fonts (Sometimes I need to pad my Times New Roman font to a full 13 points to reach a page limit). Heck, it could all be done manually in HTML, with a web-browser engine, and saving to the interesting .rtf font symbols instead of HTML tags. Anybody know a way for me to do this?
