[Haskell-cafe] Takeover of AvlTree and COrdering

I’d like to take over Hackage packages https://hackage.haskell.org/package/COrdering and https://hackage.haskell.org/package/AvlTree. Last uploads were in 2008. Both packages fail to compile with modern GHCs; my intention is to bring them back to life. There are no maintainer contacts and no source code repository linked, so I cannot reach out to the maintainer to offer my services. Best regards, Andrew
