+allows you to Build Your Own Blocks.  It also features first class
+lists, first class procedures, and continuations.  These added
+capabilities make it suitable for a serious introduction to computer
+science for high school or college students.
+
+This package provides a @command{snap} executable calling @command{xdg-open}
+to open the application in a web browser, for offline usage.")
