# For case 2/3, configurations are imported from TARGET_DIR when TARGET_DIR is specified;
# For case 4, configurations are from XML files and saved to TARGET_DIR if it is specified;
#
# The grep process did not handle corner case when '#' is manually put right after config value as comments,
# i.e. it will be failed in the case of "CONFIG_XXX=y # some comments here "
