I used to have one subdir/repo per course PLUS a pandoc directory (on the same level) with common settings for all courses.
What’s the best approach to share the whole? One repo for everything? Or one repo for the common stuff and separate repos for each course, and use #gitsubtree?
Or just separate repos? Because subtrees seem to be rather designed for the reverse scenario.
