+anypy.sets_: sets compatibility module
+
+uses the built-in type 'set' if available, and thus avoids
+deprecation warnings. Simple usage:
+
+Change all
+    from sets import Set
+to
+    from roundup.anypy.sets_ import set
+
+and use 'set' instead of 'Set'.
+To avoid unnecessary imports, you can:
+
+    try:
+        set
+    except NameError:
+        from roundup.anypy.sets_ import set
+
+see:
