26 | 10/21/2003
|
---|
27 | - changed "/mnt/cdrom" to MNT_CDROM
|
---|
28 |
|
---|
29 | 10/18
|
---|
30 | - don't say unknown compressor if no compressor at all
|
---|
31 |
|
---|
32 | 09/17
|
---|
33 | - cleaned up logging & conversion-to-changed.txt
|
---|
34 | - cleaned up compare_mode()
|
---|
35 |
|
---|
36 | 09/16
|
---|
37 | - fixed bad malloc(),free() pairs in compare_a_biggiefile()
|
---|
38 |
|
---|
39 | 09/14
|
---|
40 | - compare_mode() --- a couple of strings were the wrong way round,
|
---|
41 | e.g. changed.txt and changed.files
|
---|
42 |
|
---|
43 | 05/05
|
---|
44 | - exclude /dev/ * from list of changed files
|
---|
45 |
|
---|
46 | 04/30
|
---|
47 | - added textonly mode
|
---|
48 |
|
---|
49 | 04/27
|
---|
50 | - improved compare_mode() to allow for ISO/cd/crazy people
|
---|
51 |
|
---|
52 | 04/25
|
---|
53 | - first incarnation
