2610/21/2003
27- changed "/mnt/cdrom" to MNT_CDROM
28
2910/18
30- don't say unknown compressor if no compressor at all
31
3209/17
33- cleaned up logging & conversion-to-changed.txt
34- cleaned up compare_mode()
35
3609/16
37- fixed bad malloc(),free() pairs in compare_a_biggiefile()
38
3909/14
40- compare_mode() --- a couple of strings were the wrong way round,
41 e.g. changed.txt and changed.files
42
4305/05
44- exclude /dev/ * from list of changed files
45
4604/30
47- added textonly mode
48
4904/27
50- improved compare_mode() to allow for ISO/cd/crazy people
51
5204/25
53- first incarnation
