> The recommended approach of distributing wheels in private repositories is by using a repository server that allows proxying/redirecting the public pypi packages to pypi, and users should be using a single --index-url pointed to that private repository (assuming the maintainer of that private repository is to be trusted). Alternatively, keep a separate requirements_private.txt around for private dependencies and add a line --index-url <my private repository>.
