 # For integration tests, we want to be able to glob() up the sources inside a nested package
 # See explanation in .bazelrc
+#
+# This script ensures that we only delete subtrees that have something a file
+# signifying a new bazel workspace, whether it be bzlmod or classic. Generic
+# algorithm:
+#   1. Get all directories where a WORKSPACE or MODULE.bazel exists.
+#   2. For each of the directories, get all directories that contains a BUILD.bazel file.
+#   3. Sort and remove duplicates.
