+SUMMARY="Clean, elegant, and pragmatic dialect of Forth"
+DESCRIPTION="Retro is a clean, elegant, and pragmatic dialect of Forth. \
+It provides a simple alternative for those willing to make a break from legacy \
+systems.
+
+The language draws influences from many sources including traditional \
+Forth systems, cmForth, colorForth, Factor, and Parable. It was \
+designed to be easy to grasp and adapt to specific uses."
