       w_scan -	a universal ATSC and DVB blind scanner

       w_scan -fa -c _COUNTRY_ID_ [ options ]
       w_scan -fc -c _COUNTRY_ID_ [ options ]
       w_scan -ft -c _COUNTRY_ID_ [ options ]
       w_scan -fs -s _SATELLITE_ID_ [ options ]

       w_scan  scans for DVB-C,	DVB-S/S2, DVB-T, ISDB-T	and ATSC channels. Any
       other program accessing the DVB hardware	(like  e.g.  VDR)  has	to  be
       closed in order to avoid	conflicts while	running	w_scan.
       w_scan  provides	the channels in	different output formats (Default: VDR
       channels.conf). For other output	formats	see OPTIONS.

       The following options are available.

       -f TYPE
	      Frontend type,
	      "a" = ATSC,
	      "c" = DVB-C,
	      "s" = DVB-S/S2,
	      "t" = DVB-T (and ISDB-T) [default]
	      Depending	on "TYPE", either of the arguments  "-s"  or  "-c"  is

       -c COUNTRY_ID
	      Mandatory	 argument  for ATSC scans, cable scans and terrestrian
	      scans, see option	-f.
	      Specifies	the country where you try to scan for channels as  up-
	      percase two letter identifier, e.g.
	      DE = Germany,
	      US = United States,
	      FR = France
	      Use "-c?"	for a list of all known	identifiers.

       -s SATELLITE_ID
	      Mandatory	argument for satellite scans, see option -f.
	      Specifies	 the  satellite	 you wish to scan as uppercase identi-
	      fier, e.g.
	      S19E2 = 19.2<degree> east,
	      S13E0 = 13.0<degree> east,
	      S0W8 = 0.8<degree> west.
	      Use "-s?"	for a list of all known	identifiers.

       -A N   specify ATSC scan	type
	      1	= terrestrial [default],
	      2	= cable,

       -o N   VDR channels.conf	format
	      6	= VDR-1.2 .. VDR-1.6 [default],
	      7	= VDR-1.7 (for DVB-S2 support)

       -X     generate zap/czap/xine output instead of VDR channels.conf.

       -x     generate initial tuning data output for  (dvb-)scan  instead  of
	      VDR channels.conf.

       -k     generate channels.dvb for	kaffeine instead of VDR	channels.conf.

       -L     generate VLC xspf	playlist (experimental)

       -M     mplayer output instead of	vdr channels.conf

       -G     generate output for Gstreamer dvbsrc plugin

       scan cable (DVB), Germany:

       scan aerial (DVB), France:
	      w_scan -ft -c FR

       scan cable (ATSC), United States:

       scan aerial (ATSC), United States:
	      w_scan -fa -A1 -c	US

       use output format VDR-1.7:
	      w_scan [ OTHER OPTIONS ] -o 7

       use output format kaffeine:
	      w_scan [ OTHER OPTIONS ] -k

       use output format zap/czap/xine:
	      w_scan [ OTHER OPTIONS ] -X

	      w_scan [ OTHER OPTIONS ] -x
	      NOTE:  w_scan also performs full scans, so there is generally no
