+Count the number of objects (used meshes) in the scene.
+For b3d files, instead use Poikilos' fork of b3view:
+b3view Snail.b3d --count-meshes --exit
+
+Requires: Blender (>=2.8)
+
+
+Usage:
+- Paste this script into a new text file in a text editor panel
+  (If you don't know how to get there, see the HowTo file in
+  the utilities/blender directory at
+  github.com/poikilos/EnlivenMinetest).
+- "Text", "Run Script".
