+# This test is used to verify that the Buildability of a set of nodes
+# is unaffected by various querying operations on those nodes:
+#
+# 1) Calling exists() on a Node (e.g. from find_file) in a BuildDir
+#    will cause that node to be duplicated into the builddir.
+#    However, this should *not* occur during a dryrun (-n).  When not
+#    performed during a dryrun, this should not affect buildability.
+# 2) Calling is_derived() should not affect buildability.
+# 3) Calling is_pseudo_derived() may cause the sbuilder to be set, and
+#    it may caues the builder to be set as well, but it should not
+#    adversely affect buildability.
