# 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.
#
