 Overriding icons, templates, et cetera

-|app| allows you to override the static resources, like icons, templates, javascript, etc. with customized versions that you like.
-All static resources are stored in the resources sub-folder of the calibre install location. On Windows, this is usually
-:file:`C:/Program Files/Calibre2/resources`. On OS X, :file:`/Applications/calibre.app/Contents/Resources/resources/`. On linux, if you are using the binary installer
-from the calibre website it will be :file:`/opt/calibre/resources`. These paths can change depending on where you choose to install |app|.

-For example, if you wanted to change the icon for the :guilabel:`Remove books` action, you would first look in the built-in resources folder and see that the relevant file is
-:file:`resources/images/trash.png`. Assuming you have an alternate icon in PNG format called :file:`mytrash.png` you would save it in the configuration directory as :file:`resources/images/trash.png`. All the icons used by the calibre user interface are in :file:`resources/images` and its sub-folders.
