+The blocks can be filled with text, equations, figures etc.  The resulting
+slides are similar to the ones produced with LaTeX beamer, but more flexible.
+Sequential unconvering of elements is supported.  A compiler script is
+provided which compiles each slide separately, this way avoiding long compile
+times.")
