S ) �DebParta� 'Part' of a .deb binary package.
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') ).

md5sums. Fails if the control part does not contain a 'md5sum' file.
Keys of the returned dictionary are the left-hand side values of lines
in the md5sums member of control.tar.gz, usually file names relative to
the file system root (without heading '/' or './').
The returned keys are Unicode objects if an encoding is specified,
otherwise binary. The returned values are always Unicode.z('%s' file not found, can't list MD5 sumsrk z

DebFile objects have the following (read-only) properties:
- version debian .deb file format version (not related with the
contained package version), 2.0 at the time of writing
for all .deb packages in the Debian archive
- data DebPart object corresponding to the data.tar.gz (or
other compressed or uncompressed tar) archive contained
in the .deb file

other compressed tar) archive contained in the .deb
