Z:englobe-dpkg-man--493671-In some very old archives, the/es

In some very old archives, the files in the control tarfile may optionally be in a B subdirectory. In that case, the B subdirectory will be in the control tarfile too, and the control tarfile will have only files in that directory. Optionally the control tarfile may contain an entry for `B<.>', that is, the current directory.
