hackage-revdeps

Command-line tool to list Hackage reverse dependencies.

It is different from how Hackage itself tracks them: this tool accounts for all package components, including tests and benchmarks, and counts dependencies only across the latest releases. The approach is roughly equivalent to what packdeps.haskellers.com does.
