     This reads the metadata for a plugin from a branch or directory containing
     the plugin and reports it to stdout.
+
+    Plugins with no setup.py will be skipped. Plugins with a setup.py that
+    tries to install or otherwise run code may fail to probe - this command
+    deliberately lets that interrupt the scan: fix the plugin or don't probe
+    it.
