+  // following:
+  //  - Figure out where you should add your code. Do NOT just pick a random
+  //    location "which works".
+  //  - Document the dependencies apart from compile-time-checkable ones. What
+  //    must happen before your new code is executed? Does your new code need to
+  //    run before something else? Are there performance reasons for executing
+  //    your code at that point?
+  //  - If you need to create a (persistent) object, heap allocate it and keep a
+  //    |scoped_ptr| to it rather than allocating it on the stack. Otherwise
+  //    I'll have to convert your code when I refactor.
+  //  - Unless your new code is just a couple of lines, factor it out into a
+  //    function with a well-defined purpose. Do NOT just add it inline in
+  //    |BrowserMain()|.
+  // Thanks!
