Your iPod is mounted at $opts{mount}, ok ?
*********************************************************
This tool creates the default directory tree on your iPod
and creates an *empty* GNUtunesDB (..or convert your old
iTunesDB to a new GNUtunesDB).

You only have to use this command if
    -> You never used GNUpod with this iPod
 or -> You did an 'rm -rf' on your iPod

btw: use 'gnupod_addsong -m $opts{mount} --restore'
     if you lost your songs on the iPod after using
     gnupod_INIT.pl (..but this won't happen, because
     this tool has no bugs ;) )

Usage: gnupod_INIT.pl [-h] [-m directory]

   -h, --help              display this help and exit
       --version           output version information and exit
   -m, --mount=directory   iPod mountpoint, default is \$IPOD_MOUNTPOINT
   -d, --disable-convert   Don't try to convert an existing iTunesDB
   -g, --fwguid=HEXVAL     FirewireGuid / Serial of connected iPod (passed to mktunes.pl)
   -f, --france            Limit volume to 100dB (For French-Law/People)
                           Maximal-volume without this is ~104dB (VERY LOUD)
                           *WARNING* This works only for iPods running
                           Firmware 1.x (1st & 2nd generation)
                           You can also use mktunes.pl '--volume PERCENT'
                           to adjust the volume (Works with Firmware 1.x AND 2.x)
       --noask             Do not wait for any user input
