How export code structure of node? (for hook_install())

I believe I've seen this functionality before but I can't find it.

I've created a few nodes using Add content Type (admin/structure/types/add) and I would like to export the defining code so that I can import those same structures into other implementations using hook_install();

Is there a module that does this? Looking for something similar to the DB Structure code exported by the Schema Module. I think I've seen it before, but I can't remember where.

thanks,
