+# Tests for the :: operator in dependency declarations, which allows multiple
+# dependency groups with the same target.  Each group is evaluated on its own,
+# independent of the other groups.
+#
+# This is useful for targets that are updatable, such as a database or a log
+# file.  Be careful with parallel mode though, to avoid lost updates and
+# other inconsistencies.
+#
+# The target 1300 depends on 1200, 1400 and 1500.  The target 1200 is older
+# than 1300, therefore nothing is done for it.  The other targets are newer
+# than 1300, therefore each of them is made, independently from the other.
