+***
+There are changes detected after vendoring libwebrtc from our local copy
+of the git repo containing our patch-stack:
+$MOZ_LIBWEBRTC_SRC
+
+Typically this is due to changes made in mercurial to files residing
+under third_party/libwebrtc that have not been reflected in
+moz-libwebrtc git repo's patch-stack.
+
+The following commands should help remedy the situation:
+  ./mach python $SCRIPT_DIR/extract-for-git.py $EXTRACT_COMMIT_RANGE
+  mv mailbox.patch $MOZ_LIBWEBRTC_SRC
+  (cd $MOZ_LIBWEBRTC_SRC && \\
+   git am mailbox.patch)
+
+After adding the new changes from mercurial to the moz-libwebrtc
+patch stack, you should re-run this command to verify vendoring:
+  bash $0
+"
+FILE_CHANGE_CNT=`hg status third_party/libwebrtc | wc -l | tr -d " "`
+if [ "x$FILE_CHANGE_CNT" != "x0" ]; then
+  echo "$ERROR_HELP"
+  exit 1
+fi
+
+
+echo "Done - vendoring has been verified."
