 #### Tips
 * The `--` operator causes all following arguments to be treated as positional
   arguments, even if they look like options. This is useful when setting config

 * Keys like `nssCompiler` and `installDir` work best as global options

 * `user.cfg` files are intentionally ignored by git. Do not include them in
