|
---|
| 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 |
