+# Usage:
+# This script will check append every filename in blacklist
+# to every directory name in search_folders. Resulting paths
+# will then be checked if they exist. Files that exist will
+# get appended with 'NoDisplay=true'.
+#
+# Note: You can use environment variables in search_directories,
+# but you mustn't use them in blacklist.
