Report only mode

I would like to run peep in a way that acquires all the tarballs from the requirements file, possibly by downloading them or pulling from a cache, hashes them, and reports if everything matches, but doesn't actually install them. It would be nice if this additionally checked that the requirements tree was complete. This would be a great check to put in a CI job, and would give me confidence that I didn't break something when I changed the requirements file.

PS: It would be ever better (especially for the CI job) if running peep check (or whatever it is called) followed by peep install wouldn't download everything twice somehow.

@mythmon - Maybe if it put all the files in checks in /tmp, then checks there before re-downloading you could avoid an extra download? For the rest, this sounds like a new command such as ./peep check-reqs or something.

That's exactly what I want, a new command. In a normal installation, Peep will only download things once right now. This Issue is for a check command (or a dry run flag, or something), that will just check requirements.

The second part is that once these are all downloaded it would be a shame if they got downloaded a second time if I proceeded to actually install them. The pip download cache can probably deal with that.
