+Name:          conduit-resumablesink
+Version:       0.1
+Synopsis:      Allows conduit to resume sinks to feed multiple sources into it.
+Description:
+    @conduit-resumablesink@ is a solution to the problem where you have a @conduit@
+    sink and you want to feed multiple sources into it as each source is exhausted.
+    This is essentially the opposite of the ResumableSource functionality supplied
+    with conduit.
