That's a very good point Alex, we need to define exactly what the goals (and therefore metrics) are and then compare each proposed solution in terms of those metrics. From what I understand the metrics would be:
1. Can the installer be run without any dependencies other than perhaps a package manager?
2. How many steps are involved in installation/how difficult is it?
3. Can the tool self-update (or update via a package manager)?
4. Can clj
/`clojure` commands run without any dependencies?
5. How fast does clj
/`clojure` run? e.g. running simply clj -h
should be basically instant
6. Can users run clj
/`clojure` commands from both PS and cmd.exe?
7. Is the solution easy to maintain?
