<description>
Registers a file removal of the [param target_path] internal path to the PCK. This is mainly used for patches. If the file at this path has been loaded from a previous PCK, it will be removed. The [code]res://[/code] prefix for [param target_path] is optional and stripped internally.
Writes the files specified using all [method add_file] calls since the last flush. If [param verbose] is [code]true[/code], a list of files added will be printed to the console for easier debugging.
Creates a new PCK file at the file path [param pck_path]. The [code].pck[/code] file extension isn't added automatically, so it should be part of [param pck_path] (even though it's not required).
