[Nix-dev] Question about "package sets"

[Karn Kallio]

Thanks for the replies!

I am working on a Nix expression for Ur/Web http://www.impredicative.com/ur/ 
which is compiled with MLton.  Noticing the recent ocamlPackages expression by 
Marco ( thanks for sharing by the way ! ) prompted the question of  whether 
Ur/Web belongs in a mltonPackages "package set".

MLton has a very low release frequency and relatively few programs so I 
suppose a mltonPackages is not called for.

By the way, thank you very much to all the people who have invented and 
developed Nix and NixOS!
