gromit 20041213-9 (s390x binary) in ubuntu bionic

 Gromit enables you to make annotations on your screen.
 .
 This is especially useful when making presentations, to highlight
 things or point out things of interest.
 .
 Gromit is XInput-Aware, so if you have a graphic tablet you can
 draw lines with different strength, color, erase things, etc.
