+## install bb
 $ bash <(curl -s https://raw.githubusercontent.com/borkdude/babashka/master/install)
-$ bb '(vec (dedupe *in*))' <<< '[1 1 1 1 2]'

+$ cat ~/.babashka/prelude.clj
+(defn directory? [f]
+  (.isDirectory (io/file f)))

+$ export BABASHKA_PRELOADS="(load-file \"$HOME/.babashka/prelude.clj\")"
