- implement use of different intervals as source for cloning
   * use 'woechentlich' if available and no backup exists for 'daily'
   * add 'prefer_latest' to prefer different interval, that's newer than
     ours
   * or add 'prefer_same_interval' instead?
- implement detection of partial backups
3. detect unfinished backups
sven / markierung
   - wie seht der Marker aus?
      -> .ccollect-YEAR-MM-DD.HHmm.pid (like the directory)
   --> assume incomplete, when we did not finish.
   --> means it's complete,when rsync was successful
---> partial implemented in 0.5.2 (commented out)
- do not check by name, but by time
   * is ls -t posix?
   * also check: -p -1
- do sed-time check:

1.2. replace sed?
compare timing:
_echo () { echo "$name $msg" }
and create
_techo () { echo "$timestamp $name $msg" }
perhaps create
_eecho () { _techo "ERROR $msg" }
?

- ccollect Zeitausgabe verbessern
   - Wofuer wie lange gebraucht
   * rm
   * klonen (gibt es so ja nicht)
   Wenn Summary angegeben ist am Ende ausgeben
- add --version, -V
- do we want rsync -H by default?
- add source/ignore_failed_pre_exec
- add source/ignore_failed_post_exec

ssh / port change:
   change rsync_extra format
add note for
   09:24 < telmich> Obri: ~/.ssh/config!


Documentation:
- hint: backuping backup
- update documentation:
   - german doc?
   - exit pre/post exec -> error codes (after implementation!) (in 0.4)
   - write about fast changing fs
- Variables:
   source_$n
   no_sources
   name
- changed naming of sources:
   YYYYMMDD-HHMM.PID (better readable)

config:
   set destination-base
   /etc/ccollect/defaults/source_config
