<title>Description</title>
<para>
The command <command>fix</command> generates Nix expressions from
expressions is Fix's own high-level language. While Nix expressions are
very primitive and not intended to be written directly, Fix expressions
are quite easy to write.
The command <command>nix-instantiate</command> generates
(low-level) store expressions from (high-level) Nix expressions.
