# BackupPC_dump: Dump a single client.
#
# DESCRIPTION
#
-# Usage: BackupPC_dump [-i] [-f] [-d] [-e] [-v] <client>
+# Usage: BackupPC_dump [-i] [-f] [-F] [-I] [-d] [-e] [-v] <client>
#
# Flags:
#
#
# -f Do a full dump, overriding any scheduling.
#
+# -I Do an increment dump if the regular schedule requires a
+# full or incremental, otherwise do nothing (a full is done
+# if no dumps have yet succeeded)
+#
+# -F Do a full dump if the regular schedule requires a
+# full or incremental, otherwise do nothing
+#
# -d Host is a DHCP pool address, and the client argument
# just an IP address. We lookup the NetBios name from
# the IP address.
