+<para>The command <command>nix-install-package</command> interactively

+with the MIME type <literal>application/nix-package</literal> in a web
+browser so that it is invoked automatically when you click on
+<filename>*.nixpkg</filename> files.  When invoked, it restarts itself
+in a terminal window (since otherwise it would be invisible when run
+from a browser), asks the user to confirm whether to install the
+package, and if so downloads and installs the package into the user’s
