# A thin wrapper around the `cloc` system call
# The CLOC project is at http://cloc.sourceforge.net/ and can be installed on OSX using homebrew:
#     brew install cloc

# DANGER: not covered by tests

    # Should be safe from injection because of the `Dir.exist?` check.
    Open3.capture2("#{@command_name} --csv --quiet #{directory} 2> #{error_log_name}")
