    cat <<USAGE
Usage: $script [options]

Options (defaults are in brackets):

    -s <number>      Starting number ($nstart)
    -i <number>      Increment number ($nstep)
    -m <number>      Maximum number ($nmax)
    -z <number>      Additional number of leading zeros ($zeros)

    -f tiff,pnm,pgm  Output format ($format)*
    -d <dpi>         Resolution ($dpi)
    -t <threshold>   white threshold for B/W scanning ($threshold)
    -c <string>      Color mode, scanner specific ($mode)+
    -e 'opts'        Explicit scanimage options, see 'scanimage --help'

    -h, -?           This help message

Examples:
    "$script -s 3 -i 2 -m 30"       - will scan into files 03.tiff, 05.tiff, ..., 29.tiff
    "$script -s 3 -i 2 -m 30 -z 2"  - will scan into files 0003.tiff, 0005.tiff, ..., 0029.tiff

--------------
* Should be set to scanner default or may cause problems,
  e. g. 'pgm' for HP LaserJet M1005 MFP and 'tiff' for Samsung SCX 4100 MFP

+ Use -c Gray for HP LaserJet M1005 MFP
  Use -c Binary for Epson
