+
+Note that the libraries produced by the build system include symbols,

+be run over the binaries before deploying them.
+
+Building with default options may be performed as follows:
+
+  ./mach build
+
+This will produce a debug build (much more suitable for developing against the
+SpiderMonkey JSAPI). To produce an optimized build:
+
+  export MOZCONFIG=$(pwd)/mozconfig.opt
+  ./mach build
+
+You may edit the mozconfig and mozconfig.opt files to configure your own build
+appropriately.
