MaterialX from a directory of usual PBR maps

[AntoineSfx]

What is  your method to create a .mtlx file, or maybe some other method in Stage to create a material, from a collection of files that respects the PBR naming convention, but doesn't come with a pre -made .mtlx file ? 

I know it's probably a one liner script but I'd rather use something that is tested. I'm assuming you can create a minimal mtlx file from just the maps; looking at some sample mtlx files, it looks like a two stage graph where the uv coordinate are passed to each PBR map, and each map is passed to its matching entry in the PBR shader.
