Enable use as a library

[joonas-fi]

It would be great to use rsync server as a library in other Go projects.

Is this done with #11, or is there anything else you’re planning on doing before this issue should be closed? :)

[joonas-fi]

Great question!

How about docs, should we just link to the PR for the code example? I have nothing else in mind. (That reminds me, the code example is outdated w.r.t. the module slice. I'll update it when I get back home.)

[stapelberg]

Or maybe we add a minimal server example? Should only be a few lines of code :)

[joonas-fi]

In README.md or as an example binary under cmd/?

[stapelberg]

Ideally as a testable example that shows up in godoc and is verified to compile using go test: https://go.dev/blog/examples :)

lol thank you, once again I'm learning from you, I've spat out Go code for years but never learned about "testable examples" 😄
