Hello,

Thanks for all the great work on pip-tools! I like the way that the project is heading (pip-compile and pip-sync look pretty cool).

I just noticed that the latest release has removed pip-review. I was wondering what the new equivalent is (as I found this tool very useful)?

eg. every night I build a new pyvenv, install required pip libraries and run pip-review to send an email out to the devs letting them know if any libraries require upgrading.
