-    * ``formats_modtimes(date_format)`` -- return a comma-separated list of colon_separated items representing modification times for the formats of a book. The date_format parameter specifies how the date is to be formatted. See the date_format function for details. You can use the select function to get the mod time for a specific format. Note that format names are always uppercase, as in EPUB.
-    * ``formats_paths()`` -- return a comma-separated list of colon_separated items representing full path to the formats of a book. You can use the select function to get the path for a specific format. Note that format names are always uppercase, as in EPUB.

     * ``not(value)`` -- returns the string "1" if the value is empty, otherwise returns the empty string. This function works well with test or first_non_empty. You can have as many values as you want.
     * ``list_difference(list1, list2, separator)`` -- return a list made by removing from `list1` any item found in `list2`, using a case-insensitive compare. The items in `list1` and `list2` are separated by separator, as are the items in the returned list.
