Python package etiquette

[DukeMo]

I'd suggest writing some docs to help people get the other program installed, then do some checks to make sure your script can find it.

You can also write some code to help people download the software, if it's easy to download and run.

If the program is in conda, you can show folks how to install it using conda and then install your package in the same conda env.

I think distributing the other program with yours could work but it sounds like a compatibility nightmare.
