<title>Description</title>
<para>
The command <command>nix-pull</command> obtains a list of
pre-built store paths from the URL
<replaceable>url</replaceable>, and for each of these store
paths, registers a substitute derivation that downloads and
unpacks it into the Nix store. This is used to speed up
installations: if you attempt to install something that has
already been built and stored into the network cache, Nix can
transparently re-use the pre-built store paths.
</para>
<para>
The file at <replaceable>url</replaceable> must be compatible
with the files created by <replaceable>nix-push</replaceable>.
