-When `raise_runtime_errors` is set to `false` sprockets will not check that dependencies of assets are declared properly. Here is a scenario where you must tell the asset pipeline about a dependency:
-
-If you have `application.css.erb` that references `logo.png` like this:
-
-```css
-#logo { background: url(<%= asset_data_uri 'logo.png' %>) }
-```
-
-Then you must declare that `logo.png` is a dependency of `application.css.erb`, so when the image gets re-compiled, the css file does as well. You can do this using the `//= depend_on_asset` declaration:
-
-```css
-//= depend_on_asset "logo.png"
-#logo { background: url(<%= asset_data_uri 'logo.png' %>) }
-```
-
-Without this declaration you may experience strange behavior when pushing to production that is difficult to debug. When you have `raise_runtime_errors` set to `true`, dependencies will be checked at runtime so you can ensure that all dependencies are met.
