+version:             0.1
+synopsis:            Educational drawing canvas for FP explorers.
+description:         This package is an experimental teaching tool that
+                     provides the foundation for presenting functional
+                     idioms with graphical metaphors. The OpenGL canvas
+                     boilerplate is abstracted away to a simple interface,
+                     which allows to focus on program logic instead of the
+                     graphics API. It's also arguably fun.
