Well, is cool to change the comand

[jamlfy]

This will help much when the command console is not directly ie

$ ./vendedor/0.9.4/exiftool
Syntax:  exiftool [OPTIONS] FILE

Consult the exiftool documentation for a full list of options.

How to call would look like

var exiftool = require('exiftool')('my-comand-exiftool');
exiftool.metadata(...);
