TODO and WHISHLIST:

- add a CUI and/or a GUI to edit configuration 
- add check for timestamp of each single file??
- add use of lockfile/unlock (used in { } definitions, in conjunction with
  a prerotate script that stop output of program to logfile and to a postrotate
  script that restart output of program to new logfile)
- add firstaction/endscript (lastaction/endscript) to run a script 
  before ALL (after ALL) operations [i.e. before expanding metavars...] 
  This may be useful to mount/umount some remote backup volume
- add stronger checks for wildcards and all entries by user
- Add use of something like:
  internal_variable=`awk -F ! '/^rc_variable/ { print $2 }' < $i` ???
- Add MAIL, DIR_OWN, DIR_GRP, DIR_PERM in main RC file too??
- Add controls on main RC file. If some variable is not defined, correspondant 
  functionality must be deactivated.(show a warning in some output)
- 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 parameters: [no]missingok,[un]lock
- 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

missingok
              If the log file is missing, go on to the  next  one
              without   issuing   an   error  message.  See  also
              nomissingok.
