Sync Cocalc with Local Machine using Rsync
This shows how to use rsync over ssh to use your cocalc files offline.
BUT trouble can arise (for instructors only) if you don't exlcude your course file.
Do `ls -a` and look for a file ending in .course.
Then exclude this from the rsync command by adding
--exclude ML.course
where the name of your course replaces ML.
