Yeah, I too was hoping for something substantital, e.g. a description of how to allocate and manage a pseudo-terminal (especially since I'll be needing that for a project of mine quite soon). I'll probably be looking at the st(1) source code, then.

I'm not at all an experienced Unix programmer though so take it with a grain of salt. Would be happy to hear about any defects or possible improvements.
