Cabal and GHC: the big picture

[Oleg Grenrus]

package.db directory has only .conf files, but those conf files point to 
directories with interface and object files.
I think every tool puts the interface and object files next to .conf files.

./package.db is the "index",

./aeson-2.2.3.0-3b4881079a148ac154e9112c43bd71f61140bdb9e78660803e826af798de2108
./aeson-2.2.3.0-9bfa3c3833e85d9e62afa4f60b2820c47e8c3382991299ab624dedb682bb786a
...

is the data.

Also global package db is somewhat similar with index at e.g. 
/opt/ghcup/.ghcup/ghc/9.10.1/lib/ghc-9.10.1/lib/package.conf.d and data 
at /opt/ghcup/.ghcup/ghc/9.10.1/lib/ghc-9.10.1/lib/x86_64-linux-ghc-9.10.1
