I am creating a tool that analyzes a set of python package's source distributions. I am wondering if it is possible to use pip (or any other module) to download the source distribution tarball without installing or building it. I am going to process a lot of source distributions making manually downloading them individually from pypi.org a very tedious solution. Essentially I want something like:
>pip download_sdist foo
Successfully downloaded foo-1.2.3.tar.gz
