// I (viettrungluu) am in the process of refactoring |BrowserMain()|. If you
// need to add something above this comment, read the documentation in
// browser_main.h. If you need to add something below, please do the
// 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!
// TODO(viettrungluu): put the remainder into BrowserMainParts
