Usage: reflib -i INPUT_FILE [-f FORMAT] [-o -|OUTPUT_FILE]


-i, --input <file>             Input file to process

-o, --output <file>            Output file to save. Use '-' for STDOUT

-f, --format <reflib-format>   Override or set the file output type (if omitted the outfile filename
                               is used to determine the format)

-v, --verbose                  Be verbose when processing

--version                      Print CLI version and exit

-h, --help                     This help screen
