The interface of this class tries to mimic that of the TarFile module in
the standard library.
ArFile objects have the following (read-only) properties:
- members same as getmembers()
NÚrc C sP g | _ i | _|| _|| _|pt ¡ | _|du rd}|| _|dkr&| ¡ dS dS )aŠ Build an ar file representation starting from either a filename or
an existing file object. The only supported mode is 'r'.
The encoding and errors parameters control how member
names are decoded into Unicode strings. Like tarfile, the default
encoding is sys.getfilesystemencoding() and the default error handling
scheme is 'surrogateescape'.

Implements most of a file object interface: read, readline, next,
readlines, seek, tell, close.
ArMember objects have the following (read-only) properties:
- name member name in an ar archive
