That doesn't seem to work. I quoted the part of the man page that the
'-' is used to pass only a single PDF into pdftk via stdin and thus the
xargs thing seems not to fly.

$ cat I-A-files.txt | xargs -0 pdftk cat output I-A.pdf verbose
Error: No input files.  Exiting.
Errors encountered.  No output created.
Done.  Input errors, so no output created.

Thanks
