# Description of test files for tarlz:
# test.txt.tar.lz:   1 member (test.txt).
# t155.tar[.lz]:     directory + file + link + eof, all with 155 char names
# tar_in_tlz1.tar.lz 2 members (test.txt.tar test3.tar) 3 lzip members
# tar_in_tlz2.tar.lz 2 members (test.txt.tar test3.tar) 5 lzip members
# test_bad1.tar.lz:  truncated at offset 6000 (of 7495)
# test_bad2.tar.lz:  byte at offset 6000 changed from 0x56 to 0x46
# test3.tar:         3 members (foo bar baz) + 2 zeroed 512-byte blocks
# test3_dir.tar.lz:  like test3.tar.lz but members /dir/foo /dir/bar /dir/baz
# test3_dot.tar.lz:  like test3.tar.lz but members ./foo ./bar ./baz
# test3_bad1.tar:    byte at offset  259 changed from 't' to '0' (magic)
# test3_bad2.tar:    byte at offset 1283 changed from 't' to '0' (magic)
# test3_bad3.tar:    byte at offset 2559 changed from 0x00 to 0x20 (padding)
# test3_bad4.tar:    byte at offset 1283 changed from 't' to '0' (magic)
#                    byte at offset 2307 changed from 't' to '0' (magic)
# test3_bad5.tar:    510 zeros + "LZ" prepended to test3.tar (bogus lz header)
# test3_bad1.tar.lz: byte at offset    2 changed from 'I' to 'i' (magic)
# test3_bad2.tar.lz: byte at offset   49 changed from 0x49 to 0x69 (mid stream)
# test3_bad3.tar.lz: byte at offset  176 changed from 0x7D to 0x6D (mid stream)
# test3_bad4.tar.lz: combined damage of test3_bad2.tar.lz and test3_bad3.tar.lz
# test3_bad5.tar.lz: [71-134] --> zeroed (first trailer + seconf header)
# test3_bad6.tar.lz: 510 zeros prepended to test3.tar.lz (header in two blocks)
# test3_eof1.tar.lz: test3.tar.lz without eof blocks
# test3_eof2.tar.lz: test3.tar.lz with only one eof block
# test3_eof3.tar.lz: test3.tar.lz with one zeroed block between foo and bar
# tlz_in_tar1.tar:   1 member (test3.tar.lz) first magic damaged
# tlz_in_tar2.tar:   2 members (foo test3.tar.lz) first magic damaged
# ug32chars.tar.lz:  1 member (foo) with 32-character owner and group names
