Example not working (need more documentation) about bredxbred

[dlazesz]

Ok. Problem solved. It was my fault.

The correct invocation is: cat input.txt | wordcount/main.xbred > output.txt

The following problems occured:

1. Wrong netcat version. Should be a check for it! (I know I should RTFM more carefully.)
2. Need to enable debuging to catch the errors (not documented): export XBRED_DEBUG="on"
3. Because the asynchronous behaviour there is a delay between "xbred: done" and the actual writing of the result.
4. Some cleanup script would be useful in the case of failure: killall awk; killall nc; rm -rf work/ && mkdir -p work/{fs,jm,sort}
5. bredfs write uses non-interactive ssh session, so ~/.bashrc is not executed and bred is not found when the PATH variable is updated in it to contain bred. Should be documented...

I created PR #15 to resolve the issue.
Please consider merging it.
