I've been working on a bootloader-based backup script, and in the process of designing it, I have been using the "text2screen" application for doing just that. Fortunately, one of the other bootloader scripts that I have seen also used it, which is where I found out about this app, as well as rudamentary usage.
Yet, despite seeing it used, and using it myself, I cannot find any official documentation on it! I have seen a couple of forum posts use it in passing, but nothing more formal.
The absolute best thing I have is running -h on the app itself, which gives a rudimentary listing of all of its functions.

Is there an official guide to this(in the wiki perhaps?) or should I start to make one? And, if I need to make one, how should I go about doing so?
