Hi, for some reasons, I need to vendor pex in my own application, basically I vendor all my 3rd party packages in a _vendor folder and regex replace the import (like https://github.com/pradyunsg/vendoring/blob/7d304aa15dffe85a1378bf8dcef89e7240fe652c/src/vendoring/tasks/vendor.py#L61-L69) It works for other packages (they are much simpler) but failed for pex, the fact is that pex also vendoring some packages, any suggestions on how to rewrite the imports for the packages vendored inside pex ?
