TODO and WHISHLIST:

- add a CUI and/or a GUI to edit configuration 
- add check for timestamp of each single file??

- Reengegnerize use of main rc file: reading variables; what variables can be used
  in this file; what variables can be overridden in other config files and what can't.

- Improve report message
- Add "include" support to virott*

- IDEA:
  same logfile in two configfiles (adding '[tar]collate' 
  option)
  if I have a logfile in monthly and same file in weekly I can:
  rotate weekly 4 times a logfile (i.e. on a little volume)
  archive monthly all 4 rotated old logfiles in same file 
  (i.e. on a bigger backup volume). rottlog will concatenates all four files
  and then will archive this newly created file.
  It's incompatible with logpart option. If weekly file is not rotated this 
  method isn't too useful.
- Add use of gettext? 
- Add in install.sh script capability to add a crontab entry for LOG_OWN
- A messaging system to be able to read some particular information about
  logfile modifying in e-mail message
