Re: configurable bash script to launch Clojure available

I had a launch script (which I've now lost due to my own clumsiness)
that defaulted to a repl if given no file options, and always loaded a
.clojurerc.clj file before starting a repl (whether it was by default
or specifically asked via -r).  This allowed me to load repl-utils and
get *print-length* set up before getting a prompt.  But if a file was
named with [no] -r, it was run with no repl.  It used appropriate
combinations of clojure.lang.Repl or clojure.lang.Script and file
paths to make this happen.

As far as I can tell this is impossible with clojure.main, which
appears to only allow loading a file *or* starting a repl.  Am I
missing a method to support this, or should I go back to using
Script/Repl?

Launch a repl with no command-line-arguments:

        clj

Run a script:

        clj my-script

Run a script with command line args:

        clj my-script 1 2 3

Load an init file from classpath then run a repl:

        clj --init @my-init.clj --repl

Load an init file from classpath then run a repl with command line args:

        clj --init @my-init.clj --repl 1 2 3



        clj --init @my-init.clj my-script 1 2 3

Load two init files and run a repl with command line args:

        clj --init @my-init.clj --init my-script --repl 1 2 3

Given the clj script I posted earlier (which uses clojure.main directly) all of the following are possible. I think one of these covers the case you're asking about. If not, please let me know. Load an init file from classpath and run a script with command line args: I recognize that having this documented at http://clojure.org/repl_and_main will be very helpful to everyone. I'm working on that and I'll upload it before the end of this weekend.
