+# REWRITE RULES
+
+*rewrite* is an object where keys are regular expressions and values are
+rewrite rules if the expression matches. Rules may contain references to
+captures of the expression.
+
+Regular expression and replacement follow ECMA-script rules.
+
+If no expression matches, the format output is left unchanged.
+
+Invalid expressions (e.g., mismatched parentheses) are skipped.
