printf attr format arg1 ... argN prints the arguments
arg1,...,argN according to format with the attibutes attr.

Erasing
type
val erase : loc -> unit
erase Above erases everything before the position of the cursor.
erase Below erases everything after the position of the cursor.
erase Screen erases the whole screen.
Cursor
val set_cursor : int -> int -> unit
set_cursor x y puts the cursor at position (x,y), x
indicating the column (the leftmost one being 1) and y being the
line (the topmost one being 1). If x <= 0, the x coordinate
is unchanged; if y <= 0, the y coordinate is unchanged.
val move_cursor : int -> int -> unit
move_cursor x y moves the cursor by x columns (to the right
if x > 0, to the left if x < 0) and by y lines (downwards if
y > 0 and upwards if y < 0).
val save_cursor : unit -> unit
save_cursor() saves the current position of the cursor.
val restore_cursor : unit -> unit
restore_cursor() replaces the cursor to the position saved
with save_cursor().
Scrolling
val scroll : int -> unit
scroll n scrolls the terminal by n lines, up (creating new
lines at the bottom) if n > 0 and down if n < 0.
