Is your feature request related to a problem? Please describe.

I just went to install/run the latest Topiary after being on v3.x from Nixpkgs & my configuration @ .topiary is not working. Naturally, I went to man topiary with no return. topiary --help clued me on a TOPIARY_CONFIG_FILE env variable, however, without a manpage I couldn’t figure out what values I needed. This isn’t an ideal UX.

Describe the solution you'd like

Ship both a manpage for the CLI tool, but also another for the configuration so it can be read separately. I personally use rst2man from Docutils, but any tool (or manually writing) can work. In some ways Nickel’s | doc … can self-document, but there are no docs & it isn’t exposed to the user in a digestible format.

Describe alternatives you've considered

Use w3m in another split to look up the documentation… but this will require internet.
