<para>
|
|
The command <command>nix-instantiate</command> generates
|
|
(low-level) store expressions from (high-level) Nix expressions.
|
|
It loads and evaluates the Nix expressions in each of
|
|
<replaceable>files</replaceable>. Each top-level expression
|
|
should evaluate to a derivation, a list of derivations, or a set
|
|
of derivations. The paths of the resulting store expressions
|
|
are printed on standard output.
|

<para>
|

This command is generally used for testing Nix expression before
|

they are used with <command>nix-env</command>.
