The attached patch extends the ppm2tiff tool with an option

 -m mode open the output.tif with 'mode', e.g. a for append

This makes it easy to put multiple PNM images, or e.g djpeg outputs, into a single TIFF like:

        djpeg 1.jpg | ppm2tiff -m a -c jpeg:90 output.tif
        djpeg 2.jpg | ppm2tiff -m a -c jpeg:90 output.tif
        ...
        djpeg 9.jpg | ppm2tiff -m a -c jpeg:90 output.tif

Since there is only one useful mode option, I suggest that the '-m a' option be changed to a simple flag like '-a' for append. Can you incorporate that in your patch?
