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.
