My attempts to test this yield errors looking like this:

```
$ pandoc --defaults `pwd`/defaults --latex-engine=lualatex 
--template=my_client.latex my_source_file.pdc -o my_result_file.pdf
pandoc: unrecognized option `--defaults'
Try pandoc --help for more information.
```
looking at the --help output yields this:

```
$ pandoc --help | grep default
  -D FORMAT             --print-default-template=FORMAT                 
                        --print-default-data-file=FILE                  
                        --default-image-extension=extension
```

but no `--defaults` switch.  What am I missing here, please?
