 * Test archive contains the following entries with only MSDOS attributes:
 *   'abc' -- zero-length file
 *   'def' -- directory without trailing slash and without streaming extension
 *   'def/foo' -- file in def
 *   'ghi/' -- directory with trailing slash and without streaming extension
 *   'jkl'  -- directory without trailing slash and with streaming extension
 *   'mno/' -- directory with trailing slash and streaming extension
 *
 * Seeking reader should identify all of these correctly using the
 * central directory information.
 * Streaming reader should correctly identify everything except 'def';
 * since the standard Zip local file header does not include any file
 * type information, it will be mis-identified as a zero-length file.
