[users] Simple Gemini server for testing in the current directory?

[Ben Goldberg]

My stargazer[1] has an option for this. If you run `stargazer -d` it'll 
server files out of the current directory and do file listing. It 
auto-generates certs and sticks them in `~/.local/share/stargazer`. Hope 
that helps ?.
