Curious if you tried to contribute this to pip?

This could be a neat feature to have in pip.

e.g.:

pip freeze -r requirements.txt --build-wheels

It's a critical tool for us, I'm not sure including it in a project with longer release cycles like pip would fit our needs.

Maybe if it becomes stable enough we could consider it, but it's been in constant development since 2 years and I'm not confident enough yet.

I think this is a handy tool and would be a good addition to pip. The last commit to this repo was half a year ago. Maybe you want to reconsider this decision?

[flupke]

I have nothing against the idea, but unfortunately have 0 time to devote its realization. So if anyone wants to do it, please do :)

@dstufft - what do you think about adding this to pip?

[obestwalter]

Actually ... forget about this. This does not really belong into pip. I was thinking that pip maybe could do the dependency resolution in a different way, but after @Adaephon-GH opined that you can basically do anything in a setup.py the only way to do that "cleanly" is to do it like freeze-requirements: install everything in a fresh virtualenv and see what happened ...
