.



10/21/2003
- changed "/mnt/cdrom" to MNT_CDROM

10/18
- don't say unknown compressor if no compressor at all

09/17
- cleaned up logging & conversion-to-changed.txt
- cleaned up compare_mode()

09/16
- fixed bad malloc(),free() pairs in compare_a_biggiefile()

09/14
- compare_mode() --- a couple of strings were the wrong way round,
  e.g. changed.txt and changed.files

05/05
- exclude /dev/ * from list of changed files

04/30
- added textonly mode

04/27
- improved compare_mode() to allow for ISO/cd/crazy people

04/25
- first incarnation
