+#@ The typical usage for this tool is:
+#@
+#@ Install cross toolchain (do this only once per system)
+#@
+#@  build/install-build-deps.sh --arm
+#@
+#@  you may also want to:
+#@   build/install-build-deps.sh
+#@   build/linux/install-arm-sysroot.py (should already be done by hooks)
+#@   sudo apt-get install g++-multilib  gcc-multilib
+#@
+#@
+#@  build chrome with the cross toolchain
+#@  chrome-setup.sh configure-chrome
+#@  chrome-setup.sh make-chrome
+#@  chrome-setup.sh make-nacl    (optional)
+#@  chrome-setup.sh package-chrome
+#@  now copy the chrome tarball (chrome-arm.tgz) to your are device
