+
+Reads from a file or from a string passed to it describing additional options in JSON or YAML. (Should I support other options?)
+
+For scripts that require significant numbers of input parameters where they are often re-used, it isn't sensible to require people to specify ten flags on the command line. Offering a JSON/YAML file reader simplifies their life by providing re-usable config files.
