characters except for the chksum field which is treated as if
it was filled with spaces. According to the GNU tar sources,
some tars (Sun and NeXT) calculate chksum with signed char,
which will be different if there are chars in the buffer with
the high bit set. So we calculate two checksums, unsigned and
signed.

aÒ Create a TarInfo object from the result of os.stat or equivalent
on an existing file. The file is either named by `name', or
specified as a file object `fileobj' with a file descriptor. If
given, `arcname' specifies an alternative name for the file in the
archive, otherwise, the name is taken from the 'name' attribute of
'fileobj', or the 'name' argument. The name should be a text
string.

a! Add the file `name' to the archive. `name' may be any type of file
(directory, fifo, symbolic link, etc.). If given, `arcname'
specifies an alternative name for the file in the archive.
Directories are added recursively by default. This can be avoided by
setting `recursive' to False. `filter' is a function
that expects a TarInfo object argument and returns the changed
TarInfo object, if it returns None the TarInfo object will be
excluded from the archive.
