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 || _ d | _ y r )_DebPart__member _DebPart__tgz)selfmembers r __init__zDebPart.__init__c s r c fd} j j j }t j j | d dd }|t v s|t k( s |t k( rE|dk( r |ddg }n j } t j |d _ j S t d |z j S # t j t j f$ r}t d |z d}~ww xY w) zReturn a TarFile object corresponding to this part of a .deb package.
