freeglut3-dbg 2.8.1-2 (s390x binary) in ubuntu xenial

 GLUT is a window system independent toolkit for writing OpenGL programs.
 It implements a simple windowing API, which makes learning about and
 exploring OpenGL programming very easy.
 .
 GLUT is designed for constructing small to medium sized OpenGL programs,
 however it is not a full-featured toolkit, so large applications requiring
 sophisticated user interfaces are better off using native window system
 toolkits like GTK+ or Motif.
 .
 This package contains debugging symbols useful for tracing bugs in the
 freeglut3 package.
