* nix-env now maintains meta info (from the `meta' derivation
attribute) about installed packages in user environments. Thus, an operation like `nix-env -q --description' shows useful information not only on available packages but also on installed packages. * nix-env now passes the entire manifest as an argument to the Nix expression of the user environment builder (not just a list of paths), so that in particular the user environment builder has access to the meta attributes. * New operation `--set-flag' in nix-env to change meta info of installed packages. This will be useful to pass per-package policies to the user environment builder (e.g., how to resolve collision or whether to disable a package (NIX-80)) or upgrade policies in nix-env (e.g., that a package should be "masked", that is, left untouched by upgrade actions). Example: $ nix-env --set-flag enabled false ghc-6.4
