-<para>The command <command>nix-pack-closure</command> packs the
-contents of the store paths <replaceable>paths</replaceable> and
-<emphasis>all their dependencies</emphasis> into a single file, which
-is written to standard output.  (That is, it
-<emphasis>serialises</emphasis> <replaceable>paths</replaceable>.)
-The output can then be unpacked into the Nix store of another machine
-using <command>nix-unpack-closure</command>.</para>
-
-<para>Together, <command>nix-pack-closure</command> and
-<command>nix-unpack-closure</command> provide a quick and easy way to
-deploy a package to a different machine.  However, as the output of
-<command>nix-pack-closure</command> tends to be rather large (since it
-contains all dependencies), it’s not very efficient.
-<command>nix-push</command> and <command>nix-pull</command> are more
-efficient, but are also a bit more cumbersome to use.</para>

-closure is a single file read from standard input.  See the
