+# packagespec.mk should be included at the end of your main Makefile,
+# it provides hooks into packagespec targets, so you can run them
+# from the root of your product repository.
+#
+# All packagespec-generated make targets assume they are invoked by
+# targets in this file, which provides the necessary context for those
+# other targets. Therefore, this file is not just for conveninence but
+# is currently necessary to the correct functioning of Packagespec.
+
+# Since this file is included in other Makefiles, which may or may not want
+# to use bash with these options, we explicitly set the shell for specific
+# targets, in this file, rather than setting the global SHELL variable.
