<p>If you have Nix installed on your machine, this build and all
its dependencies can be unpacked into your local Nix store by
doing:</p>

<pre>$ gunzip < [% HTML.escape(build.nixname) %].closure.gz | nix-store --import</pre>

or to download and unpack in one command:

<pre>$ curl [% c.uri_for('/closure' build.id product.productnr) %] | gunzip | nix-store --import</pre>

<p>The package can then be found in the path <tt>[%

archive lacks a signature”, you should make sure that you have
sufficient access rights to the Nix store, e.g., run the
command as <tt>root</tt>.</p>
