Yes, sorry about the crossover. Both would be useful, but I was thinking
manpage.

Exactly what I was thinking.

Something like:

/dev	Major number	Minor numbers

st	5		   2 low bits are control bits
			00 - rewind on close, file mark on write.
			01 - no rewind on close, file mark on write.
			10 - rewind on close, file mark on write, unload.
			11 - control device, usable without media.


etc...
