-        // This has an interesting implication: it means that this rule cannot
-        // be used to update targets during match. Specifically, we cannot be
-        // executed for group resolution purposes (not a problem) nor as part
-        // of the generated source update. The latter case can be a problem:
-        // imagine a code generator that itself may need to be updated before
-        // it can be used to re-generate some out-of-date source code. As an
-        // aside, note that even if we were somehow able to communicate the
-        // "for install" in this case, the result of such an update may not
-        // actually be "usable" (e.g., not runnable because of the missing
-        // rpaths). There is another prominent case where the result may not
-        // be usable: cross-compilation.
