+""" These tests demonstrate pytest marker use for finding and running tests.
+
+    Usage examples from this file:
+        pytest -v -m marker_test_suite                 # Runs A, B, C, D
+        pytest -v -m marker1                           # Runs A
+        pytest -v -m marker2                           # Runs B, C
+        pytest -v -m xkcd_code                         # Runs C
+        pytest test_markers.py -v -m "not marker2"     # Runs A, D
+
+    (The "-v" will display the names of tests as they run.)
+    (Add "--collect-only" to display names of tests without running them.)
