For new users who want to get their feet wet right on the first day, I'd
suggest this (after they make sure they've got Java installed):
#. Download `lein`, drop it into your ~/bin, and `chmod +x` it if
necessary,
#. `lein version` (so it installs and thus creates ~/.lein directory (see
next step))
#. `touch ~/.lein/profiles.clj`, and into that file put `{:user {:plugins
[[lein-exec "0.3.1"]]}}` (or whatever the current version of [lein-exec] is
when you're reading this. :) )
[lein-exec]: https://github.com/kumarshantanu/lein-exec
Now you can create your "hello world" about as simply as with P{erl,ython}:
#. create a ~/wherever/foo.clj file,
#. into it goes `(println "hi")`, then
#. run it in the prescribed way: `lein exec foo.clj`.
