+Litorgy enables *communication* between programming languages and
+between people.
+
+Litorgy provides:
+- communication between programs :: Data passes seamlessly between
+     different programming languages, text, and tables.
+- communication between people :: Data and calculations are embedded
+     in the same document as notes explanations and reports.
