cli (clj)

THIS IS A LEGACY FUNCTION and is deprecated. Please use clojure.tools.cli/parse-opts in new applications. Parse the provided args using the given specs. Specs are vectors describing a command line argument. For example: ["-p" "--port" "Port to listen on" :default 3000 :parse-fn #(Integer/parseInt %)] First provide the switches (from least to most specific), then a doc string, and pairs of options. Valid options are :default, :parse-fn, and :flag. See https://github.com/clojure/tools.cli/wiki/Documentation-for-0.2.4 for more detailed examples. Returns a vector containing a map of the parsed arguments, a vector of extra arguments that did not match known switches, and a documentation banner to provide usage instructions.
