Comment:
This was how I did it at first, but then that perfectionist in me started to scream that there must be a way to not have that extra space there :) If you insist - I can change it though.
Also, there is actually only one supported command line argument `-c` (there is also `-h` for help, but we can skip that one). Do you think it makes sense to still have `OPTS` here? Maybe for the potential new arguments that might be added in the future releases?
