+# Implement a macro glog_library() that the BUILD file can load.
+
+# By default, glog is built with gflags support. You can change this behavior
+# by using glog_library(with_gflags=0)
+#
+# This file is inspired by the following sample BUILD files:
+# https://github.com/google/glog/issues/61
+# https://github.com/google/glog/files/393474/BUILD.txt
