Comment:
Thanks for the review, I made the recommended changes. Uses the `go` build-style now.
Also removed the `soju` system user as it looked like more work than necessary.
I think I made the mistake of doing `make doc/soju.1` rather than using `scdoc` in `post_install()`, but other than that I think it's done.
