Slightly modified version of https://github.com/defunkt/repl/blob/master/bin/repl script, adjusted for tlarepl

repl

#!/usr/bin/env ruby

# repl(1) -- sometimes you need a repl
#
# repl is an interactive program which tenderly wraps another,
# non-interactive program.
#
# For example:
#
#   $ repl redis-cli
#   >> set name chris
#   OK
#   >> get name
#   chris
#
# If you have rlwrap(1) installed you'll get the full benefits of
# readline: history, reverse searches, etc.
