Hello, I'm teaching a class where I have a big monolithic file for all the lectures. Right now I export each lecture as a subtree from the file itself, but I would like to do it from a Makefile. Is it possible to export a subtree from the command line? if so, how do I specify the subtree that I want? Thanks, Alan -- OpenPGP Key ID : 040D0A3B4ED2E5C7
