+    Rules to build the ONOS GUI
+
+    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.
+
+    Also note that the onos-gui.tar contains files from //tools/gui and //web/gui, so the files are placed into
+    the sandbox at the proper locations and then returned as a tar ball.
