by the build farm. See e.g., http://catamaran.labs.cs.uu.nl/dist/nixpkgs-0.8/nixpkgs-0.7pre2302/; the user can click on packages, and they will be installed (assuming the `application/nix-package' MIME type has been associated with `nix-install-package'). Nix expressions are no longer involved: a "package" is just a pointer to a manifest, and the top-level store derivation to be added to the user environment. This makes these packages independent from Nix expression evolution. Note that we install the store derivation ($drvPath), not the resulting output path ($outPath). This is equivalent, except that installing the derivation maintains the back-link from the output path to the derivation that built it. This is useful for maintenance. * Automatically re-exec in an xterm so that the user sees something when `nix-install-package' is run from a browser.
