+# DESCRIPTION
+# This script is intended to address issues for re-execution of 
+# tasks. The test results are saved in ./reexeclogs. Force build
+# logs are saved with prefix "force". Build failure logs are saved with
+# prefix "failed". Log files with prefix "initial" are used to save
+# initial build logs for each recipe. Log files with prefix "clean" are
+# used to save logs of clean task after testing for a recipe is finished.
+#
