why the || '' ??
the help sub doesn't seem to exit/die so it is buggy imo. when you check
command args and fail, you should exit, not issue a help screen and
continue. what if there is output from the program to be sent somewhere,
then it would be prefixed by all the help noise. i see your point in
initializing that to a defined value but that shouldn't ever continue if
help is printed.
