Hello. What are the best practices in deprecating packages on Hackage? I've seen packages marked "DEPRECATED" in the synopsis field on Hackage, and one could add GHC "deprecated" pragmas for every module, but is that the best one can do?

You may also send an e-mail to Hackage's maintainers asking them to mark your package as deprecated. Packages deprecated this way do not show on Hackage's package list. Cheers, -- Felipe.
