+Name: Desugar, transforming Java 8 bytecode to be Java 7 compatible
+Short Name: desugar
+URL: It's part of Bazel build system (https://github.com/bazelbuild/bazel).
+     Also, go/desugar for @google.com account owners

+Description:
+Desugar is a Google-developed open-source Java library used by the build process
+to transform Java 8 bytecode to Java 7. It is used to enable Java 8 features
+such as lambda experssions for Chrome on Android.
+
+Local Modifications:
+Desugar.jar is the "Desugar_deploy.jar" target defined in
+[bazel]src/tools/android/java/com/google/devtools/build/android/desugar/BUILD
+
+Update instructions (requires @google.com account):
+- Build Desugar_deploy.jar by running
+blaze build --java_launcher //third_party/java/jdk:jdk_launcher\

Using Bazel rather than blaze is fairly straight-forward. Please update
instructions (and prebuilt jar) to use bazel.

Done.
