+// The global value of STRIP_LOG. All the messages logged to LOG(XXX)
+// with severity less than STRIP_LOG will not be displayed. If it can
+// be determined at compile time that the message will not be printed,
+// the statement will be compiled out.  STRIP_LOG can be set to a value
+// between 0 and 4 where 0 logs all messages and 4 logs no messages.
+//
+// Example: to strip out all INFO and WARNING messages, use the value
+// of 2 below. To make an exception for WARNING messages from a single
+// file, add "#define STRIP_LOG 1" to that file _before_ including
+// base/logging.h
+//
+// Example: In addition it's possible to remove the dependency on the base
+// library if an executable or library currently only depends upon logging.
+//
+// # A library that only includes "base/basictypes.h" and "base/logging.h".
+// cc_library(name = "mylibrary",
+//            srcs = [ "mymodule_that_logs.cc" ],
+//            deps = [ "//base" ])
+//
+// The build rule for mylibrary can be modified as shown in the following...
+//
+// # A library with logging disabled.
+// cc_library(name = "mylibrary_no_logging",
+//            srcs = [ "mymodule_that_logs.cc",
+//                     "/base:logging.h" ],
+//            deps = [ "//third_party/stl" ],
+//            copts = [ "-DSTRIP_LOG=4" ] )
+//
+// Finally if it's desirable to strip all logging from an executable build
+// using...
+//
+// blaze build --copts="-DSTRIP_LOG=4" //mypackage:mylabel
