   main options:

positive.code: * init options:
  ** `-co`, `--compile-opts` _edn_ Options to configure the build, can be an EDN string or system-dependent path-separated list of EDN files / classpath resources. Options will be merged left to right.
  ** `-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, can be an EDN string or system-dependent path-separated list of EDN files / classpath resources. Options will be merged left to right.
  ** `-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
  ** `-i`, `--init` _path_ Load a file or resource
  
negative.code: * init options only for `--compile`:
  ** `-O`, `--optimizations` _level_ Set optimization level, only effective with `--compile` main option. Valid values are: `none`, `whitespace`, `simple`, `advanced`
  ** `-o`, `--output-to` _file_ Set the output compiled file
  ** `-w`, `--watch` _path_ Continuously build, only effective with the `--compile` main option. Specifies a system-dependent path-separated list of directories to watch.
  * 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.
