This looks great :)

Perhaps this should be:
Usage: java -jar clojure.jar [option*] [file-arg* [-- [arg*]]]
or does it make sense to allow args without file-args?

Excellent :)

This "Clojure" seems out of place. I wonder if it would make sense to
suppress it if the repl is loading stuff, or if "-e" is used?

I think this could just as well load all the files in the order they
appear on the command line. It seems easier to me to explain "the
files are loaded in order" rather than "the files listed after the
first file are loaded in order, followed by the first file."

Could you supply command line args here? If so, I suppose you can
ignore my comment about the Usage.

I like it.
