	//: Clones this input source provider.
	CL_InputSourceProvider *clone();

	//: Returns a new inputsource provider object that uses a new path relative to current one.

	//: Creates a new file entry

	//: Adds a file to zip archive.
	//- <p>File is not added to zip file until it save() is called.</p>
	//param filename: Filename of file.

	//: Saves zip archive.
	//param filename: Filename of zip archive. Must not be used to save to the same as loaded from.
	//- <p>If no filename parameter was passed, it will modify the zip
	//- archive loaded at construction time. It does this by creating a
	//- temporary file, saving the new archive, deletes the old one and
	//- renames the temp file to the original archive filename.</p>
	//-
	//- <p>If the archive was created instead of loaded, a filename must
	//- be specify a filename. Likewise, if saving to same archive as
	//- loaded from, a filename must not be specified. Doing so will
	//- cause the save operation to fail.</p>
