# Caveat: this was run before the [BackupChanges = False] config 
# preset was added to avoid slow __bkp__ folder prunes.  With the
# new preset, the apply step runs faster; most of its time here 
# was spent in a prior-backup delete, which is slow in Android 11.
#
# UPDATE: this example was rerun with Mergeall 3.3 and the new 
# preset, so its runtimes no longer include the prune overhead.
