positive.code: 
  * With no options or args, runs an interactive Read-Eval-Print Loop
  * init options:
  ** `-cf`, `--compile-opts` _edn_ Options to configure the build
  ** `-d`, `--output-dir` _path_ Set the output directory to use. If supplied, `cljsc_opts.edn` in that directory will be used to set ClojureScript compiler options
  ** `-re`, `--repl-env` _env_ The REPL environment to use. Built-in supported values: `nashorn`, `node`, `browser`, `rhino`. Defaults to `browser`
  ** `-ro`, `--repl-opts` _edn_ Options to configure the repl-env
  ** `-t`, `--target` _name_ The JavaScript target. Configures environment bootstrap and defaults to `browser`. Supported values: `node` or `nodejs`, `nashorn`, `webworker`, `none`
  * init options only for `--main` and `--repl`:
  ** `-e`, `--eval` _string_ Evaluate expressions in string; print non-`nil` values
  
negative.code: ** `-w`, `--watch` _path_ Continuously build, only effective with the `--compile` main option
  * main options:
  ** `-` Run a script from standard input
  ** `-c`, `--compile` _[ns]_ Run a compile. If optional namespace specified, use as the main entry point. If `--repl` follows, will launch a REPL after the compile completes. If `--server` follows, will start a web server that serves the current directory after the compile completes.
  ** `-h`, `--help`, `-?`  Print this help message and exit
  ** `-m`, `--main` _ns_ Call the `-main` function from a namespace with args
  ** `-r`, `--repl` Run a repl
