+# top.make is included in the Makefile in the build directories.
+# It DOES NOT include the vm dependency info in order to be faster.
+# It's main job is to implement the incremental form of make lists.
+# It also:
+#   -builds and runs adlc via adlc.make
+#   -generates JVMTI source and docs via jvmti.make (JSR-163)
+#   -generate sa-jdi.jar (JDI binding to core files)
+
+# It assumes the following flags are set:
