A .deb package is considered as made of 2 parts: a 'data' part (corresponding to the possibly compressed 'data.tar' archive embedded in a .deb) and a 'control' part (the 'control.tar.gz' archive). Each of them is represented by an instance of this class. Each archive should be a compressed tar archive although an uncompressed data.tar is permitted; supported compression formats are: .tar.gz, .tar.bz2, .tar.xz . When referring to file members of the underlying .tar.gz archive, file names can be specified in one of 3 formats "file", "./file", "/file". In all cases the file is considered relative to the root of the archive. For the control part the preferred mechanism is the first one (as in deb.control.get_content('control') ); for the data part the preferred mechanism is the third one (as in deb.data.get_file('/etc/vim/vimrc') ). c C s || _ d | _d S �N)�_DebPart__member� _DebPart__tgz)�self�memberr r r �__init__W s zDebPart.__init__c sp | j dk�rj| jj}tj�|�d dd� }|tksF|tksF|tk�r^t j dk �r|dk�rz@ddl }ddl � ddl }|jddg|j|jd� fd d �d �}W n2 ttfk r� } ztd | ��W 5 d}~X Y nX |�| j�� �d }|jdkr�td |j ��|�|�}n| j}ztj|dd�| _ W n8 tjtjfk �rZ } ztd| ��W 5 d}~X Y nX n td| ��| j S )z�Return a TarFile object corresponding to this part of a .deb package.
