void DjVuDocEditor::remove_file ( const GUTF8String id,
bool  remove_unref = true 

Removes a DjVu file with the specified id#.

If some other files include this file, the corresponding INCL# chunks will be removed to avoid dead links.

If remove_unref# is TRUE#, the function will also remove every file, which will become unreferenced after the removal of this file.
