MDTools.exe doc is inconsistent with tool help

Not urgent, but I noticed that when running the mdtools.exe executable without any arguments, the following arguments are shown:

This does not match the list of arguments (or the case/naming) from the PDF documentation - I assume the .exe just needs a quick update on the allowed params, since it includes a `--PD` argument that is not in the docs, and doesn't break out the `--op`, for example.
