[Haskell-cafe] ANN: custom-hackage

[Niklas Hambüchen]

Hello Albert,

thanks for this! Please don't be reluctant with this, it is very
appreciated.

I have updated the script to use the paths as you described, and it
seems to work quite well. The fact that all tars land under package/
even makes is easier to use.

It would be great if you could give it another try.
