        --[no-]clean-whitespaces     If enabled: removes trailing whitespaces, 
                                       if disabled: suppresses reporting trailing whitespaces
        --[no-]add-missing-newline   If enabled: adds missing newline to EOF,

    -v, --version                    Show version

If --[no-]clean-whitespaces is not given, trailing whitespaces will be reported but files will not be changed.
If --[no-]add-missing-newline is not given, missing EOF newlines will be reported but files will not be changed.

Example:

# Remove trailing newlines and add missing EOF newlines in all .cpp and .h files under directory projects/
$ source-scrubber -d projects -e .cpp -e .h --clean-whitespaces --add-missing-newline
