Jürgen / Bob,
Do we have other utilities that let the user pass raw mode values? I'd rather not have this in ppm2tiff if it is not an established pratice. Of course -a for append is fine.
It is true that supporting the same output selection options as 'tiffcp' is best. Quite a lot more work to implement though.

Sure. There are more - possibly useful - mode options, though. The list of options given in TIFFOpen(3TIFF) like l,b to change the byte order, m to disable memory mapped files, perhaps h to skip some parsing overhead (untested).

options are libtiff version dependent. (to be released soon) Libtiff 4
offers more mode options.
Are you willing and able to send a patch for the manual page as well?
