Selecta is interactive-only, getting user input from /dev/tty, so this would be really hard; I can't even think of how to do it without complex chroot shenanigans. :( The only non-interactive stuff it has is --version and --help.

Speaking of which, it actually didn't have a --version option (there were no version numbers until an hour ago). @sos4nt, can you update the PR to v0.0.2?
