// Package term provides support functions for dealing with terminals, as
// commonly found on UNIX systems.
//
// Putting a terminal into raw mode is the most common requirement:
//
//	oldState, err := term.MakeRaw(int(os.Stdin.Fd()))
//	if err != nil {
//	        panic(err)
//	}
//	defer term.Restore(int(os.Stdin.Fd()), oldState)
//
// Note that on non-Unix systems os.Stdin.Fd() may not be 0.

// mode and returns the previous state of the terminal so that it can be
// restored.
