+- `simple-verifier` - a simple mDL reader for age attestations.
+  - This application requests either {`age_over_21` and `portrait`} or 
+    {`age_over_18` and `portrait`}. It's intended to demonstrate use of the 
+    `MdocReaderPrompt` class, which allows any app to easily act as a reader app for 
+    the common age-verification use case.
