Don't explode into a 20 line stack trace if the kll file is formatted incorrectly. Instead simply show the error message and exit with an error code (which will stop the rest of a make command). A misformatted file is most likely a user error so showing the full backtrace for debugging is not necessary. The file and line number should (hopefully) be enough to fix the parsing error.simple
