How can I include pipreqs in my requirements.txt file. (so meta, I know)

Is there a way to include additional packages in the `requirements.txt` file that are not imported into the project? For example, including `pipreqs` in the outputted `requirements.txt`.

Thanks!

No source file, test, or entry point is named in the issue. Start by locating the CLI path that generates requirements.txt and review how imported packages are selected. Done means there is a documented way to include an additional package such as pipreqs in the generated output, with behavior covered by an appropriate test.
