qrsyncmgr - GUI front end to manage your rsyncs, based on Qt6

qrsyncmgr is a GUI program based on Qt6 to help you manage different rsyncs.
rsync is a tool to synchronise a 2nd (backup) directory with a master directory.
It is just a front end to rsync. The date of the last successful run of each 
rsync is stored with the definitinon.

rsync does not support a bi-directional synchronisation. Look into e. g. unison 
for that.

Syncing to a remote machine is not supported.
The remote machine has to be mounted before.

The program has only one screen.

qrsyncmgr is released under the MIT license.
