There isn't an official way to do this now but you can package a
ClojureScript library (of .cljs files) into a jar and add it to the
classpath. Once on the classpath, the namespaces in the library can
then be required and used just as you would currently use clojure.set
or clojure.string.
If you mark your public functions with ^:export, even advanced optimization
will keep those functions intact.
You can campile your library into js, and distribute that file.
You can use this compiled file just as any other Closure compatible
javascript library.

The --batch flag causes it to skip your personal dotfiles, so you will
