        //We make a temporary local copy of the file.
        //TODO: 28/03/08 - This is a second approach of dealing with non-local file.
        //The first approach which is more preferable and done in SVN version 233
        //does not create a temporary local copy of the file. 
        //It uses Commons-VFS "zip://" uri scheme to directly access the non-local file.
        //This second approach is being carried out because the writing operation cannot
        //use Commons-VFS "zip://" scheme as the scheme does not support writing to 
        //zip file yet.
        //TODO: 28/03/08 - DO NOT use "tmp://" scheme to make a temporary file. 
        //as it is going to fail. The current Commons-VFS library is still buggy.
