-Node Import Truncate
-====================
+Node Truncate
+=============
-This module adds a final step at the Node Import form so users
-can choose whether to erase all nodes of a given content type
-before importing new data into it.
-
-It might be useful in cases like users periodically importing
-a CSV spreadsheet with new as well old content: this module can
-erase all previous imported data to avoid duplicate content in
-the database.
+Use this module to delete all posts from a given content type.
