Close the archive. If close_parent(true) was specified in
archive_open/4, the 
underlying entry stream is closed too. If there is an entry opened with archive_open_entry/2, 
actually closing the archive is delayed until the stream associated with 
the entry is closed. This can be used to open a stream to an archive 
entry without having to worry about closing the archive:
archive_open_named(ArchiveFile, EntryName, Stream) :-
    archive_open(ArchiveFile, Archive, []),
    archive_next_header(Archive, EntryName),
    archive_open_entry(Archive, Stream),
    archive_close(Archive).
