Usage: smartctl_tests_long [CONFIG_FILE (absolute path)]

If no CONFIG_FILE is given, HOME/.smartctl_tests_long.conf or /etc/smartctl_tests_long.conf is used. This fallback option
has to exist or the script will exit.

Configuration can be done in any file and any pre-defined variable can be overwritten.

The following are at least required for the script to work:
- SMARTCTL_TESTS_LONG_MAIL_ADDRESS="" // mail.rc has to be configured
- SMARTCTL_TESTS_LONG_DEVICES=(sda) // array of block devices (not partitions!) to check

You can copy this script to '/usr/local/bin' and use create a custom CONFIG_FILE as user. Examples can be found in '/usr/share/doc/<scriptname>'.
