Re: Reading stdin

Maybe since your input file was not in "oleo" format.  Try specifying,
for instance, list format:

    echo -e '1\t2\t3\t4\t5' | src/oleo --filter --format list

or csv:

    echo 1,2,3,4,5 | src/oleo --filter --format csv

Incidentally, if you get SEGV, try the following patch I just checked
into the cvs which tries not to print a filename for stdin.
