I've written this like a billion times because it's fun. The above code is pretty gross but it works...

It will kind of ignore commented lines, assuming those lines are commented out with //.

"""
    This script is designed to export a mass amount of MagicaVoxel .vox files
    to .obj. Unlike Magica's internal exporter, this exporter preserves the
    voxel vertices for easy manipulating in a 3d modeling program like Blender.
    
    Various meshing algorithms are included (or to be included). MagicaVoxel
    uses monotone triangulation (I think). The algorithms that will (or do)
    appear in this script will use methods to potentially reduce rendering
    artifacts that could be introduced by triangulation of this nature.
