The same problem you have with BE-modules will arise in CLI-modules. See
thread "SymLinked typo3/ext" about some trouble this hardcoded path
might produce.

You used it here:

 // Include init file:
require(dirname(PATH_thisScript).'/'.$BACK_PATH.'init.php');

which is the most important call for loading the TYPO3-framework.

lowlevel is just one specific CLI application, your own don't have
anything to do with that. I don't see how they are related, they only
use the same API.

You pass $_SERVER['argv'] to your main() method of your class and it can
handle the command line the way it wishes. AFAIK we don't have any
getopt()-like functionality in TYPO3-core, so you have to do it your own
way.
