# cljsh-test.sh is a bash shell script that tests most non-interactive use cases for cljsh.

# Use the following command to capture the annotated output of this script in a log-file
# ./cljsh-test.sh  > cljsh-test.log 2>&1

# all clojure scripts are passed to the "lein repl" server over the network/loopback 
# for eval, and the output is brought back to stdout.

# cljsh -h will give help info and does some basic diagnostics
