* Implemented Eelco V.'s `nix-env -I' command to specify the default
path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
