+display, but in the author's opinion these libraries do it almost right -
+either they eat up too much screen real estate (by not sticking to one line
+per thing that should use progress) or they try to align stuff left and right.
+
+In the author's humble opinion, the best example of just the right amount of
+information vs screen real-estate is in the Git progress output (when cloning,
+pulling, etc).  It uses one line per thing, and may display both percentage
+complete (in cases where it's known) and even throughput (for network
+transfer).
+
+This library mimics the Git way of showing progress.")
