+        Replacement is a python utility
+        that parses a yaml template and outputs text.
+
+        A 'template' is a YAML file containing a 'replacement' object.
+
+        A 'replacement' object contains a list of blocks,
+        each of which is executed in sequence.
+
+        This tool is useful in generating configuration files,
+        static websites and the like.
