-      # Destroys the records matching +conditions+ by instantiating each
-      # record and calling its +destroy+ method. Each object's callbacks are
-      # executed (including <tt>:dependent</tt> association options and
-      # +before_destroy+/+after_destroy+ Observer methods). Returns the
-      # collection of objects that were destroyed; each will be frozen, to
-      # reflect that no changes should be made (since they can't be
-      # persisted).
-      #
-      # Note: Instantiation, callback execution, and deletion of each
-      # record can be time consuming when you're removing many records at
-      # once. It generates at least one SQL +DELETE+ query per record (or
-      # possibly more, to enforce your callbacks). If you want to delete many
-      # rows quickly, without concern for their associations or callbacks, use
-      # +delete_all+ instead.
-      #
-      # ==== Parameters
-      #
-      # * +conditions+ - A string, array, or hash that specifies which records
-      #   to destroy. If omitted, all records are destroyed. See the
-      #   Conditions section in the introduction to ActiveRecord::Base for
-      #   more information.
-      #
-      # ==== Examples
-      #
-      #   Person.destroy_all("last_login < '2004-04-04'")
-      #   Person.destroy_all(:status => "inactive")

       # Deletes the records matching +conditions+ without instantiating the records first, and hence not
       # calling the +destroy+ method nor invoking callbacks. This is a single SQL DELETE statement that
       # goes straight to the database, much more efficient than +destroy_all+. Be careful with relations
