I have a directory inside my home directory, and inside it I have files with various utilities I have written over the years. So far, whenever I have installed a new version of Python, I have simply put a util.pth into site-packages. If you remove that possibility, what am I supposed to do? Every other solution is either much more complicated, or doesn't enable me to evolve my utilities inplace, or both. What am I missing? (My OS is Windows, and shortcuts don't work, I've tried.)
