johnwoodman/remoteinjector ? reverse-engineered prompt

Build me a small Python command line tool that takes a .docx file and adds a link to a remote Word template inside it.

I want to be able to point it at a normal document and give it either an http URL or an SMB path to a template, then have it save out an updated document with that remote template reference injected. It should be simple to run from the terminal, like toolname.py -w https://example.com/template.dotm file.docx, and also work with a network path if I give one.

Please make it easy to use, show a help message, and keep the script lightweight. If you need to check current docs or Word file behavior online, go ahead and do that.
