-\optrue{peephole\_optim}{no\_peephole\_optim}
-Specifies whether Nitpick should simplify the generated Kodkod formulas using a
-peephole optimizer. These optimizations can make a significant difference.
-Unless you are tracking down a bug in Nitpick or distrust the peephole
-optimizer, you should leave this option enabled.
+\opargboolorsmart{preconstr}{term}{dont\_preconstr}
+Specifies whether a datatype value should be preconstructed, meaning Nitpick
+will reserve a Kodkod atom for it. If a value must necessarily belong to the
+subset of representable values that approximates a datatype, preconstructing
+it can speed up the search significantly, especially for high cardinalities. By
+default, Nitpick inspects the conjecture to infer terms that can be
+preconstructed.

+\opsmart{preconstr}{dont\_preconstr}
+Specifies the default preconstruction setting to use. This can be overridden on
+a per-term basis using the \textit{preconstr}~\qty{term} option described above.
