# BackupPC_dump: Dump a single client.
#
# DESCRIPTION
#
-# Usage: BackupPC_dump [-i] [-f] [-d] [-e] <client>
+# Usage: BackupPC_dump [-i] [-f] [-d] [-e] [-v] <client>
#
# Flags:
#
# dhcp hosts that are no longer on the network will not expire
# old backups.
#
+# -v verbose. for manual usage: prints failure reasons in more detail.
+#
# BackupPC_dump is run periodically by BackupPC to backup $client.
# The file $TopDir/pc/$client/backups is read to decide whether a
# full or incremental backup needs to be run. If no backup is
