+>>>>> with the previous ones. The new approach is to hard-code in `scan()`
+>>>>> which of the meta types are supported in the setup file. If one is
+>>>>> defined, then `scan()` calls `preprocess()`, as [[smcv]] suggested,

+>>>>> number of supported types, or addition of arguments to existing ones,
+>>>>> can similarly be special-cased.
+>>>>>
+>>>>> The setup data structure is no longer complicated with an
+>>>>> array-of-hashes, which means this is suitable for exposing via websetup.
+>>>>> `getsetup()` has been adjusted accordingly.
+>>>>>
+>>>>> The patch can be found at the git branch described above.
