"""
This is an example application for the 'blessings' Terminal library for python.
This isn't a real progress bar, just a sample "animated prompt" of sorts
that demonstrates the separate move_x() and move_y() functions, made
mainly to test the `hpa' compatibility for 'screen' terminal type which
fails to provide one, but blessings recognizes that it actually does, and
provides a proxy.
