// =============================================================================
// The main acceptable use of extensions in the default Chrome experience (i.e.
// not installed explicitly by the user) are to implement things like the
// history or settings pages. These are things that look like web pages, load
// in response to explicit user action, and use no resources when not opened.
// If you are asking for approval to add a new built-in extension to Chrome
// (whether downloaded with the binary or downloaded later on-demand), check:
// - It must not do anything on startup. Loading extensions processes on
// startup can significantly slow things down.
// - It must not have a background page. Extension processes use a nontrivial
// amount of memory that makes them inappropriate for built-in features.
// - Avoid event pages. Some events such as navigation will be even worse than
// background pages since it will cause the extension to be frequently
// loaded and unloaded. Even if your event page is "good" now, it's
// something that is easy to regress with inocuous looking changes, so
// try to use explicit C++ invocation of the extension when reasonable.
