+    Rules to build the ONOS GUI 2
+
+    The GUI2 Angular 6 elements are built here with Angular CLI 'ng'
+    Some work is being done in the Bazel community to integrate Bazel and
+    Angular 6, (Angular Buildtools Convergence -
+    https://docs.google.com/document/d/1OlyiUnoTirUj4gecGxJeZBcjHcFr36RvLsvpBl2mxA8/preview)
+    but it is in the very early stages (Aug'18) and not yet fit
+    for production and at present it works as a replacement for Angular CLI
+    (which is not desirable).
+
+    There are plans to extend Bazel it to work with Angular CLI, and if works
+    well this Bazel file may be rearchiteced in future.
+
+    Bazel and npm are incompatibe in how they deal with files. npm likes to
+    follow links to get back to the original canonical path names, and bazel
+    uses links extensively when populating the sandbox. To get around these
+    problems, the rules that follow use filegroups to specify the files as
+    dependencies and then use a genrule to convert the files into a tar ball.
+    Once the tar ball is unrolled into the sandbox, the links are broken, but
+    the build is still hermetic since those files are referred to as dependencies in the genrule.
