Ok, I can't disagree with that :)

you checked in yesterday for S1/S2 and -D options.
In order to keep the AUTO behaviour you want and also allow for cards which
cannot handle autos I have added a new option -X which sets a noauto flag.
When this option is chosen, instead of putting an initial transponder with an AUTO
in the transponder list, several transponders are created for each allowed value of
each free parameter (which may be delivery system, modulation, fec or rolloff).
so with -X
S 12551500 V 22000000 5/6results in
initial transponder DVB-S 12551500 V 22000000 5/6 35 QPSK
initial transponder DVB-S2 12551500 V 22000000 5/6 35 QPSK
initial transponder DVB-S2 12551500 V 22000000 5/6 35 8PSK
initial transponder DVB-S2 12551500 V 22000000 5/6 25 QPSK
initial transponder DVB-S2 12551500 V 22000000 5/6 25 8PSK
initial transponder DVB-S2 12551500 V 22000000 5/6 20 QPSK
initial transponder DVB-S2 12551500 V 22000000 5/6 20 8PSK
(fec was fixed in the transponder file in this example, but delivery
system, rolloff and modulation were not)
The new S1/S2 and -D options are respected. So with -D S1, the S2
lines would not be added for example.
Using -X -D and S2/S1/S thus gives lots of flexibility for scanning.
I hope we won't run out of free letters for next command line flags we'll add :)
Sounds good to me. My recent changes to delete duplicate frequencies when lock was successful on one of them will be especially helpful in that case to speed up the scan process.

The patch also makes improvements in
parse_satellite_delivery_system_descriptor, adding rolloff and the
new S2 FECs and changes to delivery system and modulation parsing.
Thanks. You did part of the work I've intended to do :)
