-Usage: $0 [-vfpsmut] [-d depth] pdffile outdir
+Usage: $0 [-vfpsmutb] [-D DPI] [-d depth] [-F format] pdffile outdir
 Convert pdffile - a pdf of scanned facing pages - to a set of images in outdir,
 each with only one page.
 OPTIONS:
        -v: Be verbose.
        -d depth: Use given depth. Default is 1 for black and white, 8 for colour.
                Unpaper can only handle up to 8.
-       -D dpi: Use given DPI. Colour scans on library scanners are usually 300, bw 400.

+       -F extension: use the output format signified by the extension. Default is png
        -s: skip masking/trimming. Overrides -m.
        -f: Forceably redo everything.
        -p: Forceably redo pdf conversion. Implies options below, equivalent to -f.
        -m: Forceably redo masking/trimming and other preprocessing. Impiles options below.
        -u: Forceably redo unpaper processing. Implies option below. IGNORED
