# Description of test files for ddrescue:
# fox          : "The quick brown fox jumps over the lazy dog.\n"
# test.txt     : 4 copies of the GPLv2, alternating LF and CRLF line ends
# test[1-5].txt: partial copies of test.txt as recorded in mapfile[1-5]
# mapfile1     : Alternating finished/non-tried blocks of 0x800 bytes each
# mapfile2     : mapfile1 inverted (non-tried/finished)
# mapfile2i    : mapfile2 without the non-tried blocks
# mapfile3     : Alternating finished/non-tried blocks of 0x800/0x1000 bytes
# mapfile[45]  : Triphasic complement to mapfile3
# mapfile6     : mapfile1 with non-finished subsectors smaller than 512 bytes
# mapfile6j    : mapfile6 with the subsectors joined to the right blocks
# mapfile_blank: non-tried mapfile cut to the lenght of test.txt (72776)
