Browse source 
Changelog:
```
version 3.5.1
	storeBackup.pl
	- linkToRecent didn't work when used for the very first time
	  in a series
	- added option suppressInfo with key readCheckSums
	- changed the order of execution:
	  write backup -> sync -> write 'finished' -> write linkToRecent
	  -> delete old backups -> start postcommand

	storeBackupMergeIsolatedBackup.pl
	- added option --move

	storeBackupSearch.pl
	- option 'backupDir' didn't work (normally not needed)

	lib/fileDir.pl
	- more detailed error messages when copying of a file does
	  not succeed

	lib/checkParam2.pl
	- overwriting settings from config file via commandline didn't
	  work for options with parameters

	storeBackup.pl, storeBackupUpdateBackup.pl, linkToDirs.pl
	- added option --maxHardLinks

----------------------------
version 3.5.2
	storeBackup.pl
	- option --maxHardLinks was not configurable in the
	  configuration file
	- pipe buffering was changed to new needs since
	  about kernel 5.13 (relevant only if you backup devices)

	storeBackupRecover.pl
	- restoring of devices (eg. sda) didn't work because of
	  bug in option checkDevicesDir0 in storeBackup.pl when
	  using more than one directory level like "Devs/Sticks"

	storeBackupUpdateBackup.pl
	- added log file entry about number of WARNINGs and
	  ERRORs happend (like at storeBackup.pl)
