+// This file contains a map to redirect dependencies towards sysprop_library.
+// As sysprop_library has to support both Java and C++, sysprop_library internally
+// generates cc_library and java_library. For example, the following sysprop_library
+//
+// sysprop_library {
+// name: "foo",
+// }
+//
+// will internally generate with prefix "lib"
+//
+// cc_library {
+// name: "libfoo",
+// }
+//
+// When a cc module links against "foo", build system will redirect the
+// dependency to "libfoo". To do that, SyspropMutator gathers all sysprop_library,
+// records their cc implementation library names to a map. The map will be used in
+// cc.Module.DepsMutator.
